Question

A rectangular prism measures 225 inches by 315 inches by 2 inch.
Priya said, “It takes more cubes with edge length 25 inch than cubes with edge length 15 inch to pack the prism.” Do you agree with Priya? Explain or show your reasoning.

How many cubes with edge length 15 inch fit in the prism? Show your reasoning.

Explain how you can use your answer in the previous question to find the volume of the prism in cubic inches.

Answer 1

Answer:

No I don't agree with Priya

The reason why I don't agree with Priya is because 25 Inch side blocks are BIGGER than 15 inch side blocks. That means that it will take less amount of 25 inch side blocks to fill up the volume of the rectangular prism rather than 15 inch side blocks.
