Answer:
6 cm.
Step-by-step explanation:
The perimeter = 2(H + W) where H = height and W = width. So we have:
30 = 2(9 + W)
30 = 18 + 2W
2W = 30 - 18 = 12
W = 6 cm.
Answer:
1. To convert cubic inches to cubic feet we divide the figure by 1728 (there are 1728 cubic inches in a cubic foot).
2. Measure the length, width and height of the box in inches. 2. Multiply the length, width and height and divide the resulting number by 1,728. This is the container's volume in cubic feet.
