Question

A square pyramid has 2 m sides on the base. Each face is a triangle with a base of 2m and a height of 1.5 m. Explain how to find the surface area.

Answer 1

Surface area = 10m^

Area triangle : Half of the base multiplied by the height

half of 2=1

1x1.5=1.5Aarea of 1 triangle

the pyramid has 4 faces 4x 1.5=6m (lateral area)

base area 2x2=4m

total surface 6m+4m=10m
