You find the surface area of each of its six faces and add them together.
Yes. The term "surface area" as normally used for 3-dimensional objects but that does not alter its meaning. The two measures are the same.
A trapezoid is a two-dimensional shape, so it doesn't have surface area. The AREA of a trapezoid is: (Base1+Base2) X Height Divided/Over 2. For example: Imagine a trapezoid. Base 1 (top) measures 6 and Base 2 (bottom) measures 8. The height of the trapezoid from B1 to B2 is ''3''. Procedure: (6+8)x3 Divided by 2 14x3 Divided by 2 42 Divided by 2 Ans: 21^2
29.6
Area of a trapezoid: 0.5*(sum of its parallel sides)*height
