B: 132 cm

C: 156 cm

D: 276 cm

Answer 1

Area of the square pyramid =
`156\,cm^2`

Explanation:

The Surface area of the square pyramid :

Area of the four triangular faces+ Area of the square base

`=(2* Base * Height )+ (Side* Side)`

For triangle:

`Base=6\,cm\\Height=10\,cm`

Side of the square base=
`6\,cm`

Area of the figure is:

`=(2* 6 *10 )+(6* 6)\\\\=120+36\\\\=156\,cm^2`

The area of the square pyramid is :
`156\,cm^2`
