Question

Find the total surface area of this triangular prism.

Answer 1

162.4

Explanation:

bh + (s1 + s2 + s3)H is the formula, so if you plug in the numbers and follow PEMDAS you get 162.4

Answer 2

Total surface area of triangular prism:

A = base area x 2 + base perimeter x height

= 6 x 8 x (1/2) x 2 + (6 + 8 + 10) x 4

= 48 + 96

= 144 (cm2)

Hope this helps!
