What is the surface area of the rectangular prism below 7, 12, 14
Rus_ich [418]

What is the surface area of the rectangular prism below 7, 12, 14

Formula to find the surface area of the rectangular prism is:

2wl + 2lh + 2hw,

where w is width, l is length, and h is height of the rectangular prism.

Given dimension of the prism is 7, 12, 14.

So, w=7, l=12 and h= 14.

First step is to plug in the above values of l, w and h in the above formula to get the surface area. So,

Surface area of the rectangular prism =2wl + 2lh + 2hw

=2*7*12 + 2*12*14 + 2*14*7

=168+336+196

= 700

So, the surface area of the rectangular prism is 700 units².
