Answer: 25 in³
Step-by-step explanation:
We can calculate the volume of the pyramid by first calculating the volume of a prism with the same dimensions, and then dividing by 3 (all pyramids a volume that's of the volume of a prism with the same dimensions).
The volume of a prism is its base area times its height. The base would be a square, so its area is 5², which is 25. The height is 3 inches, making the prism's volume 75 in³.
The volume of the pyramid would be one-third of this value, which is 75 which is 25 in³.
Answer:
Step-by-step explanation:
When simplifying an exponent a way to do is to expand the exponent. This means that it will now be
Whenever you see an x or y on the numerator and denominator cross it out because it is the same thing as 1
When you cross out all of the x's and y's the only variable left is y in the denominator. This means that the answer is
