Question

Please helppp!

find the surface area of the triangular prism.
2cm
5cm
6cm
4cm
3cm
6cm

Answer 1

82 cm^2

Explanation:

First, find the formulas for the areas of all of the shapes shown

area of rectangles = base * height

area of triangle = 1/2 * base * height

for the triangle at the top, area = 1/2 * 5 * 2 = 5 cm^2

for the bottom triangle, area = 1/2 * 5 * 2 = 5 cm^2

for the left rectangle, area = 6 * 3 = 18 cm^2

for the middle rectangle, area = 5 * 6 = 30 cm^2

for the right triangle, area = 4 * 6 = 24 cm^2

add all of these together

5 + 5 + 18 + 30 + 24 = 82 cm ^2
