Math prodigy corrects museum exhibit error

ORIGINAL PROBLEM

A jelly bean has a volume of about 1 cubic cm.This container is half a pyramid.

Its base measures 46 cm by 23 cm and its height is 72 cm.

Here's the formula to find the volume: 1/3 x base area x height.

Now divide your answer by 2 since this is half a pyramid.

Now multiply your answer by 0.9 to account for spaces between the jelly beans.

The answer should be 22,853.

THE ERROR

The base measurements given were already for half the pyramid, so there was no need to divide the answer by 2.
