The top of a monument will be a rectangular pyramid. it will take 22 m3 of bronze to make the top that is 11 m tall. what is the missing dimension of the base of the pyramid? 1 m 2 m 3 m 4 m

To solve this problem you must apply the proccedure shown below:

1. You must use the formula for calculate the volume of a rectangular pyramid, which is:

Where is the volume (), is the area of the base and is the heigth ().

2. Now, you must solve for and substitute the values into the formula:

3. The formula for calculate the area of a rectangle is:

Where is the area, is the width and is the length. You already have the width, so you can solve for the length to calculate it:

The answer is:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
