Answer 1

Answer:

Volume of a cuboid = length × width × height

315 = 9×5 × h

h = 315/45

height is 7cm

Hope this helps.

Answer 2

Answer:

height=7 cm

Solution,

$volume(v) = 315 \: {cm}^{3} \\ length(l) = 9 \: cm \\ width(w) = 5 \: cm \\ volume = l \times w \times h \\ \: \: \: \: \: \: or \: 315 = 9 \times 5 \times h \\ \: \: \: \: or \: 315 = 45h \\ or \: h = \frac{315}{45} \\ h = 7 \: cm$

hope this helps....

Good luck on your assignment....
