Find the volume of a pyramid with a square base, where the area of the base is 15.4m^2 and the height of the pyramid is 15.6 m. Round your answer to the nearest tenth of a cubic meter.

A.) 80.1 m

B.) 62.3 m

C.) 125.7 m

D.) 97.5 m

It should be A

Step-by-step explanation:

The area of the base is 15.4m, and volume=base*height, so v=15.4*15.6, v=240.24, BUT since it's a pyramid, you have to divide by 3, which'll give you 80.08, if you round to the nearest tenth, you'd get 80.1

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

2x^2+5x+17
