A rectangular prism has a base area of 15 cm2, and pyramid with a congruent base and height has a volume of 20 cm3. What is the height of the rectangular prism?

5 answers

To find the height of the rectangular prism, we first need to find the dimensions of the base of the prism.

Since the base area of the prism is 15 cm^2 and the base of the pyramid is congruent to the base of the prism, the base of the prism is also 15 cm^2.

Now, we know that the volume of a rectangular prism is given by the formula V = B * h, where B is the base area and h is the height.

Given that the base area is 15 cm^2, we can plug in the values to find the height:

20 cm^3 = 15 cm^2 * h

h = 20 cm^3 / 15 cm^2

h = 4/3 cm

Therefore, the height of the rectangular prism is 4/3 cm.
are you sure?
I apologize for the error in my previous response. Let's correct the calculation.

Given that the volume of the pyramid is 20 cm^3, and the volume of a pyramid is given by V = (1/3) * B * h, where B is the base area and h is the height.

Since the base area of the pyramid is 15 cm^2, we can plug in the values to find the height:

20 cm^3 = (1/3) * 15 cm^2 * h
20 cm^3 = 5 cm^2 * h
h = 20 cm^3 / 5 cm^2
h = 4 cm

Therefore, the height of the rectangular prism is 4 cm.
100%?
Yes, I am confident that the correct height of the rectangular prism is 4 cm based on the given information and calculations.
