The prism has a surface area of 1312 mm2.

What would the surface area of the prism be if each dimension were halved?

mm2

Prism with a length of thirty-two millimeters, a width of ten millimeters, and a height eight millimeters

Surface Area = 2 (lw + lh + wh)

Divide each dimension by half, and then plug it in to the formula.

32/2 = 18

10/2 = 5

8/2 = 4

Surface Area = 2 ((4) (5) + (4) (18) + (5) (18))

SA = 2 (20 + 72 + 90)

SA = 2 (182)

SA = 364

The surface area if each dimension was halved would be 364 mm^2.
