Question

What is the surface area of the triangular pyramid shown?round to the nearest tenth.

Answer 1

57.6 cm/mm/m/in/ft squared

Explanation:

You will need to answer the each triangle separately which you have to use the formula 1/2*b*h

5.2*1/2(6) = 15.6

4*1/2(6) = 12

5*1/2(6) = 15*2 (2 sides)

total = 57.6 cm/mm/m/in/ft squared
