150 in²

Step-by-step explanation:

The surface area is the area of the 6 faces shown in the net.

Each face is a square with area = s² ( s is the side length )

here s = 5

surface area = 6 × (5 × 5) = 6 × 25 = 150 in²

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480
