Question
The dimensions of a right rectangular prism are 4 inches by 5 inches by 6 inches. What is the surface area, in square inches, of the prism?
- 30
- 74
- 120
- 148
The correct answer is: 148
The dimensions of right rectangular prism are 4 x 5 x 6
The surface area of prism = a(lb + bh + hl)
= 2(20 + 30 + 24)
= 2(74) = 148.
