Question

15. Find the surface area of the rectangular prism with l = 15 m, w = 16 m, and h = 4 m. (1 point)

960 m2

1,920 m2

70 m2

728 m2

16. Use the net to find the surface area of the prism.


276 m2

22 m2

522 m2

968 m2

Answer 1

1232 m^2.

Explanation:

The net consists of 2 triangles and 3 rectangles.

Area of each triangle = 1/2 * 24*7 .

Area of 1 rectangle = 25 * 19.

The other 2 have areas 24*19 and 7 * 19.

Therefore the surface area of the prism

= 2 * 1/2 * 24 * 7 + 25*19 + 24*19 + 7*19

= 1232 m^2.
