Estimate the surface area of the rectangular prism.
a) 24 cm2
b) 52 cm2
c) 64 cm2
d) 81 cm2

Step-bThe solution is 52 cm2. We can round each side length to the nearest whole number and then find the area of each face.

2 x 3 = 6

3 x 4 = 12

4 x 2 = 8

Since each face occurs twice, multiply each area by 2 and take the sum.

2(6) + 2(12) + 2(8) = 52 cm2.y-step explanation:
