Question

Find the surface area of the triangular prism below. The bases each have an

area of 6 cm2 and a perimeter of 12 cm, and the altitude is 6 cm.
6 cm
A. 84 cm
B. 24 cm
C. 40 cm
D. 60 cm

Answer 1

A. 84 cm²

Explanation:

Surface area of triangular prism = 2(base area) + (Perimeter)*height of prism

Base area = 6 cm² (given)

Perimeter = 12 cm

Altitude = height of prism = 6 cm

Plug in the values into the formula

Surface Area of triangular prism = 2(6) + (12)*6

= 12 + 72

= 84 cm²
