Brian wanted to build a wooden planter box for his garden with a volume of 32 cubic feet. If he constructed the planter with a height of 1 foot and a width of 4 feet, what should the length of the planter be, in feet?

8feet

Step-by-step explanation:

v=lwh

32=4(1)(x)

32=4x

divide both side by 4

8=x

Therefore, the length of the wooden planter box is 8ft

V=abh

V=32, width=4 and height=1

32=a*4*1

32=4a

a=8

length must be 8 ft
