Question

What is the surface area of the rectangular prism below?

16 cm 2
32 cm 2
64 cm 2
128 cm 2

Answer 1

SA= 64cm^2

Explanation:

There are 4 rectangles with dimensions 2 and 4, and 2 rectangles with dimensions 4 and 4

4(2x4)+2(4x4)=64cm^2

Answer 2

64 cm^2

Explanation:

surface area formula: 2(lw+wh+lh)

2(4*4+4*2+4*2)

2(16+8+8)

2(32)

64 cm^2
