Joshua is going to create a garden border around three sides of his backyard deck using
cinder blocks. He is going to plant a flower in each hole of the cinder block. The dimensions
of the cinder blocks are 8 inches by 16 inches by 8 inches. Each hole needs to be completely
filled with potting soil before the flowers can be planted. Potting soil is sold in 1 cubic foot
bags.
