in
18.3 in and the height of the pyramid is
15.7
in
15.7 in. Round your answer to the nearest tenth of a cubic inch.

109.5 in³

Step-by-step explanation:

1. The perimeter of the square base is given to be 18.3 inches. Since the base is a square, it can be divided by 4 to find the length of each side. This gives us 4.575 inches.

2. The formula for the volume of a pyramid is 1/3Bh. We can substitute the square of 4.575, which is 20.930625. That is substituted into the equation, making 1/3(20.930625)h inches. Additionally, the height is given as 15.7 inches, meaning we can substitute 15.7 for h. This gives us the final formula of V=1/3(20.930625)(15.7)

3. Use order of operations to solve the problem. Bh (20.930625)(15.7) is 328.6108125. Dividing this value by 3 gives 109.5369375, which rounds to 109.5 in³, which is the final answer.

it's both, now can you answer my most recent question?

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
