Question

Emilia has a pencil box that is 12 inches long, 5 inches wide, and 3 inches tall. Richard's pencil box is 8 inches long and 5 inches wide, but it is twice as tall as Emilia's pencil box. How many cubic inches larger is Richard's pencil box than Emilia's pencil box?​

Answer 1

Twice as large, or 180 cubic inches more

Explanation:

To find the volume/ cubic inches of Emilia's pencil box, multiply base x width x height.

12 · 5 · 3 = 180

Do the same with Richard's pencil box, but multiply the height by 2

12 · 5 · 3(2) = 360

Subtract 180 from 360 to get 180.

Richard's pencil box is 180 cubic inches larger than Emilia's

Hope this helps!
