Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. A right rectangular prism has a length of 15 millimeters, width of 3 millimeters, and height of 4 millimeters. What is the surface area of the prism?

Answer 1

the surface area of the prism is $234mm^2$ .

Step-by-step explanation:

Here we have , A right rectangular prism has a length of 15 millimeters, width of 3 millimeters, and height of 4 millimeters.  We need to find  What is the surface area of the prism . Let's find out:

We know that surface area of the prism = $2(lb+bw+wl)$ . According to question we have following parameters as :

$length = 15 mm\\width=3mm\\height=4mm$

Putting these values to find area of prism we get:

⇒ $Area = 2(lw+wh+hl)$

⇒ $Area = 2(15(3)+3(4)+4(15))$

⇒ $Area = 2(45+12+60)$

⇒ $Area = 2(117)$

⇒ $Area = 234mm^2$

Therefore , the surface area of the prism is $234mm^2$ .
