Start with the formula for the volume of a rectangular prism of Length, L, width, W, and depth, d.
V+=+L%2AW%2Ad Substitute V = 8 cu.ft., W =2 ft., d = 0.8 ft.
8+=+L%2A%282%29%2A%280.8%29 Simplify.
8+=+L%2A%281.6%29 Divide both sides by 1.6
8%2F1.6+=+L
highlight%28L+=+5%29
The garden is 5 feet long.
