Answer:
Part 1) [tex]V=343\ km^{3}[/tex]
Part 2) [tex]V=1,331\ yd^{3}[/tex]
Step-by-step explanation:
we know that
The volume of a cube is equal to
[tex]V=s^{3}[/tex]
where
s is the length of the cube
Part 1)
we have
[tex]s=7\ km[/tex]
substitute in the formula
[tex]V=7^{3}[/tex]
[tex]V=343\ km^{3}[/tex]
Part 2)
we have
[tex]s=11\ yd[/tex]
substitute in the formula
[tex]V=11^{3}[/tex]
[tex]V=1,331\ yd^{3}[/tex]
Answer:
a) 343 kilometres³
b) 1331 yards³
Step-by-step explanation:
The volume of a cube is calculated using the following formula, where S is the side length of the cube:
[tex]V=S^{3}[/tex]
a) Cube with side length, s = 7 kilometres
[tex]V_{a}=7^{3} \\V_{a}=343[/tex]
a) Cube with side length, s = 11 yards
[tex]V_{a}=11^{3} \\V_{a}=1331[/tex]
