Large boxes hold 3 times as much as small boxes. Layla has packed 4 large and 7 small boxes. If she has packed a total of 22.8 cubic feet, how much does a large box hold?

3.6

Step-by-step explanation:

1. 1 large=3 small

2. 4*3=12 small

3. 12+7=19 small in total

4. 22.8 cubic feet/19 small box=1.2 cubic feet per small box

5. 1.2*3=3.6 cubic feet for a large box

Double check:

3.6 as large box

1.2 as small box

(3.6*4) + (1.2*7)

=14.4+8.4

=22.8

In the end, a large box can hold 3.6 cubic feet.
