Answer:
Pool 1: 2(3)*3*3= 54 ft^3
pool 2: 2(4)*4*4= 128 ft^3
Pool 3: 2(5)*5*5= 250 ft^3
pool 4: 2(6)*6*6= 432 ft^3
Step-by-step explanation:
length can be modeled by twice the width or twice the depth which means that deapth=width,
both the width and the depth are equal, hence
L= 2x
W=X
x=3,4,5,6 (which are values for depth as well as width)
susbtitute values:
Pool 1: 2(3)*3*3= 54 ft^3
pool 2: 2(4)*4*4= 128 ft^3
Pool 3: 2(5)*5*5= 250 ft^3
pool 4: 2(6)*6*6= 432 ft^3
