Question

Find the surface area of the triangular prism.

A) 608 ft
B) 704 ft
C) 560 ft
D) 590 ft

Answer 1

I'll setup the formula and you can do the calculations.

Explanation:

you need to add up the areas of 2 rectangles (10x16), 1 rectangle on the bottom (12x16) and 2 triangles ( height = 8 and base = 12)

area of rectangle = wide x length

area of triangle = 1/2 base x height

can you compute the answer? if you need more help, send a comment

Answer 2

C

Explanation:

10*8*12 = 960

16*10 = 160

960+160= 1120

1120 ÷ 2 = 560
