Respuesta :
(1*80)^2=160 the reason you double it is because the height is 2. So the answer is 160 square feet of sand.
Answer:
[tex]160\ ft^{3}[/tex]
Step-by-step explanation:
we know that
The volume of the sandbox is equal to
[tex]V=Bh[/tex]
where
B is the area of the base of the sandbox
h is the height of the sandbox
we have
[tex]B=80\ ft^{2}[/tex]
[tex]h=2\ ft[/tex]
substitute
[tex]V=80*2=160\ ft^{3}[/tex]
