Question

Ben made a model (shown below) of the square pyramid he plans to build when he grows up. Find the surface area of the model.

Answer 1

240 m

Explanation:

Answer 2

The surface area of the model is
`SA=240\ m^(2)`

Explanation:

we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of four lateral triangles

so

`SA=10*10+4((1)/(2)(10)(7))\\ SA=100+140\\SA=240\ m^(2)`
