Q:
# A paperweight in the shape of a square pyramid has a side length of 2.7 inches. The slant height is 2.5 inches. What is the surface area of the paper weight

Accepted Solution

A:

1. To solve this problem you need to apply the formula for calculate the surface area of a square pyramid, which is shown belown:

A=2bs+b^2

A is the surface area of the square pyramid.

b is lenght of the base of the square pyramid.

s is the slant height of the square pyramid.

2. Then, you have:

b=2.7 inches

s=2.5

3. When you substitute the values above into the formula for calculate the surface area of the square pyramid, you obtain:

A=2bs+b^2

A=2(2.7 inches)(2.5 inches)+(2.7 inches)^2

A=13.5 inches^2+7.29 inches^2

A=20.79 inches^2

The answer is: 20.79 inches^2

A=2bs+b^2

A is the surface area of the square pyramid.

b is lenght of the base of the square pyramid.

s is the slant height of the square pyramid.

2. Then, you have:

b=2.7 inches

s=2.5

3. When you substitute the values above into the formula for calculate the surface area of the square pyramid, you obtain:

A=2bs+b^2

A=2(2.7 inches)(2.5 inches)+(2.7 inches)^2

A=13.5 inches^2+7.29 inches^2

A=20.79 inches^2

The answer is: 20.79 inches^2
