What is the surface area of the rectangular pyramid below?

A rectangular pyramid. The rectangular base has a length of 18 feet and width of 10 feet. 2 triangular sides have a base of 18 feet and height of 14.1 feet. 2 triangular sides have a base of 10 feet and height of 16 feet.

386.9 ft2

593.8 ft2

639.4 ft2

1,053.2 ft2

B - 593.8 ft2

Step-by-step explanation:

I also just finish the quiz and got the question right.

To find the base: 10 x 18 = 180

There are 4 lateral face, two each are conguent:

18 x 14.1 = 253.8

253.8 divided by 2 = 126.9

126.9 x 2 = 253.8

Other conguent sides:

10 x 16 = 160

160 divided by 2 = 80

80 x 2 = 160

Finally: 180 + 253.8 + 160 = 593.8 ft2
