The net of a pyramid consists of a square of side 5m; and four triangles, each with height 3m. Calculate the total surface area ofthe pyramid (square base and the four sloping sides)

Solution

Given ; side of square parts = 5m

area of square parts =side×side

= 5m×5m=25 square m

base of all triangle = 5m

hright= 3m

area of triangle =1/2 ×base ×height

=1/2×5×3

=15/2 square m

total surface area of pyramid=4×15/2+25

=30+25 =55 square m

m
