Question

What is the lateral area of a rectangular prism with a base length of 16 m, a base width of 8 m, and a height of 4 m?

Answer 1

Answer:  B. $192\ m^2$

Step-by-step explanation:

The lateral area of a rectangular prism is given by :-

$\text{Lateral Area}=2h(l+w)$, where h is the height, l is the length and w is the width of the rectangular prism.

Now, using the given information, the lateral area of the rectangular prism will be :-

$\text{Lateral Area}=2(4)(16+8)=8(24)=192\ m^2$

Answer 2

B. because you do 16*2*h + 8*2*h and you get 128 + 64 = 192
