Find the surface area of a rectangular prism. A rectangular prism with length 34 feet, width 21 feet, and height 10 feet.
a.
7140 sq. ft
b.
2528 sq. ft
c.
1264 sq. ft
d.
1814 sq. ft

b.

2528 sq. ft

Step-by-step explanation:

Surface area of rectangular prism:

A rectangular prism has length l, width w and height h. It's surface area is given by:

In this question:

We have that

So the surface area is

2528 square feet, option b.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
