Look at the picture, please I really need help on this, my class is due tomorrow

Answer 1

Answer: 160 in²

Explanation:

The surface area is the area of all the sides of the figure added together. To find the surface area of a square pyramid, we will find the area of the base square. Then, we will find the area of one triangle side and multiply it by 4. Lastly, we will add these together.

Area of a square:

A = b²

A = 10²

A = 100 in²

Area of a triangle:

A =
`(b*h)/(2)`

A =
`(10*12)/(2)`

A =
`(120)/(2)`

A = 60 in²

Adding them together to find the total surface area:

100 in² + 60 in² = 160 in²
