SA = 2lw+2hw+2lh Follow the same procedures for other questions I didn't answer for you. 1. 2(9)(12)+2(9)(9)+2(12)(9) = 594 cm² 2. 2(13)(8)+2(8)(5)+2(13)(5) = 418 units² Last 6 questions: very vague (are you referring to volume?)

supply up utilising Liberals as an opposition, or excuse. Even President George Bush sees international warming as a severe challenge. Liberals hating U.S.? i've got self belief there's a freedom of speech there? purely using fact they produce different evaluations then you definately look to have does no longer recommend that they hate the country. i think of you could desire to confirm greater to info and enable human beings have the evaluations they choose. And save the political questions interior the right area, no longer here. Btw, to those that thinks this is a 'super question': Did you recommend to declare that U.S. is responsible for 27.6% of international extensive green homestead gas emissions? if so, you could desire to declare how many of U.S. emissions that autos stands for. in the experience that your question substitute into wisely suggested you could desire to declare how lots of the worlds green homestead gas emissions that the U.S. is responsible for to make it an entire question.

all i knew is, VOLUME=width x length x height thats it...u will got the answer..... and ALWAYS remember, when dealing with the round area /surface/volume please think about [Pi] that is [22 divide by 7] or 22/7 or in rounded [3.142].... so , when comes to the cylinders...please or ALWAYS/MUST use the Pi x radius x radius x height = u will go the VOLUME answers..[not surface area] but REMEMBER, Diameter = 2 x Radius, So if u been given the Diameter value..please divide by 2, you get the radius value..thats how u would play when u got the diameter or radius value... so if u get radius value...u have to multiply by 2 to get the diameter value..so that means the DIAMETER SHOULD BE LONGER THAN THE RADIUS OF THE ROUND SURFACE/AREA..... BUT HOW ABOUT THE AREA SURFACE CALCULATIONS.. IF VOLUME OF THE CUBE IS = width x length x height , so the area surface should be different..and that is [remember...cube or its related have 4 surface] so, the surface area = l x w x l x w x l x w x l x w... so thats it...we will got 4 of [l x w]...so surface area of the cube should be the same value, [cos it was the cube] same length and same width...so that means surface area [cube] in shorter = 4 x l x w..[remember this for the CUBE formula].. and..the cylinder surface AREA....IF VOLUME IS, Pi x radius x radius x height, if the round surface area be = 2 x Pi x radius... so bt seeing the cylinder shapes..that should be, 2(pi x radius x radius) + (2 x pi x radius) x h [REMEBER this bro...] bye.. [CORRECTIONS IS WELCOMES].....

Surface Area (boxes)= 2 x height + 2 x length + 2 x width or 2 x (height + length + width) Surface area (cylinder) = 2 x (pi x radius^2) + height x 2 x pi x radius

For surface area you add up all of the measurement's and times them by 2. That way you get the answer. So for example if a question was something like ..... 4cm length , 7cm height , 2cm width , Then you would times 4 twice times 7 twice and times 2 twice then you would add them all up together and you have your surface area but be sure to show the formula.

Just because one says they hate math doesn't mean they mean hate every single bit of it in a literal manner. Not everyones gifted with perfect math skills even with studying. It's not that their "proud" of it, its that they have a hard time understanding it, and in some cases they'll get so frustrated as to just give up and find a career that doesn't take high level math.
