Question

What is the surface area of this square pyramid

Answer 1

33 ft&²

Explanation:

multiply 4x3x3 = 36 and put half of 6, then it is 33 33ft²

Answer 2

33 ft²

Explanation:

We have

the square with side s = 3ft

four triangles with base b = 3ft and height h = 4ft

The formula of an area of a square:

`A=s^2`

The formula of an area of a triangle:

`A=(bh)/(2)`

Substitute:

`A_(\square)=3^2=9\ ft^2`

`A_(\triangle)=((3)(4))/(2)=(12)/(2)=6\ ft^2`

The Surface Area:

`S.A.=A_(\square)+4A_(\triangle)\\\\S.A.=9+(4)(6)=9+24=33\ ft^2`
