If the length of the sides are doubled, the volume of the cube is 8 times the original.
Explanation: The formula for volume of a rectangular prism is v = lxwxh (l is length, w is width and h is height.) So first we find the volume of the cube, 2x2x2 = 8. Now, we double the sides, so they become 4 meters. Then we find volume of the new cube, 4x4x4 = 64. To find the relationship between the volume of the new cube and the volume of the original cube, we divide 64 by 8, which gives us 8. Therefore, the volume of the new cube is 8 times the volume of the original cube
So the actually surface area can be split up by dif parts....meaning 2 side is 2.7*3.2*2 = 17.28 2 side is 3.2*2.1*2 = 13.44 2 sides is 2.1*2.7*2= 11.34
then u add up the areas = 42.06ft^2
then u look for what is the clossest...and that is 42gt^2
