Question

What is the surface area of this rectangular prism? (5 in.Length) (5 in. Width.) (12 in. Height.)

Answer 1

So, you know that the formula to finding the surface area of a rectangle is A=2wl+2lh+2hw
The height of the rectangle is 12 in
Width=5in
Length=6in
Plug that in and see what you have arrived to.

Answer 2

Answer:  $290\ in.^2$

Step-by-step explanation:

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

$\text{Surface area}=2(lw+wh+lh)$

Given: Length = 5 in.

Width = 5 in.

Height = 12 im.

Now, the surface area of the rectangular prism will be :-

$\text{Surface area}=2(5*5+5*12+5*12)\\\\\Rightarrow\ \text{Surface area}=2(25+60+60)\\\\\Rightarrow\ \text{Surface area}=290\ in.^2$
