Question

Find the surface area of the figure.
7.4 cm
5 cm
5 cm

Answer 1

The surface area of the given figure would be
`A=103.11`.

Considering the given figure is a square pyramid, the formula for finding surface area would be
`A=a^2+2a\sqrt{(a^2)/(4)+h^2 }`.

`A=a^2+2a\sqrt{(a^2)/(4)+h^2 }`

`5^2+2*5*\sqrt{(5^2)/(4)+7.4^2 }`≈
`103.1089=103.10` ← Our Final Solution

Hope this helps!
