Question

Find the lateral area of a rectangular prism with l=6, w=4, h=2

Answer 1

40 square units

Explanation:

The surface area is given by

LA = 2(wh+lh)

where h is the height l is the length and w is the width

We do not include the top or bottom

We know l=6 w=4 and h=2

LA = 2 ( 4*2 + 6*2)

lA = 2( 8+12)

= 2 (20)

= 40
