Question

surface area of rectangular prisms practice

use the image to answer the question
1.5m, 3m, 4m

what is the surface area of the rectangular prism?

_ m^2

Answer 1

To find the surface area of a rectangular prism, you need to find the area of each individual face and then add them all together.

The rectangular prism has 6 faces: 2 rectangles with dimensions 3m x 4m, 2 rectangles with dimensions 1.5m x 4m, and 2 rectangles with dimensions 1.5m x 3m.

Therefore, the surface area of the rectangular prism is:
(2 x 3m x 4m) + (2 x 1.5m x 4m) + (2 x 1.5m x 3m)
= (24m^2) + (12m^2) + (9m^2)
= 45m^2

So, the surface area of the rectangular prism is 45m^2.
