Hi, I am having trouble visualizing this problem, if anyone can help me see it, I know how to do the integral part. A church steeple is 30 feet tall with square cross sections. The square at the base has side 3 feet, the square at the top has side 6 inches, and the sides varies linearly in between. Compute the volume. I assume the 3 feet and then 6 inches has to be in the same form so it would 36 inches and 6 inches. I also know that volume for a square would be length times width times height or one side raised to the 3rd power. I am just not sure to start.
