Question

A right rectangular prism has a length of 6 centimeters, a width of 2 centimeters, and a height of 5 centimeters. What is the surface area of the prism? Enter your answer in the box. cm²

Answer 1

For this case we have that by definition, the total surface area of a right prism is given by:$SA = ph + 2B$

Where:

p: Perimeter of the base

h: It's the height

B: It is the area of the base

So:

$B = 6 * 2\\B = 12 \ cm ^ 2\\p = 6 + 6 + 2 + 2 = 16 \ cm$

So, we have:

$SA = 16 * 5 + 2 (12)\\SA = 80 + 24\\SA = 104 \ cm ^ 2$

Answer:$104 \ cm ^ 2$
