Question

if the
length=7.3ft
width=4.2ft
height=7ft

how many cubic meters is this?

Answer 1

Volume = 7.3 * 4.2 * 7 = 214.62 cubic feet

1 inch = 2.54 cm
12 inches = 1 foot
Therefore, 1 foot = 12 * 2.54 cm = 30.48 cm

1 metre = 100 cm
Therefore, 1 foot = 30.48 / 100 metres = 0.3048 metres
So, 1 cubic foot = (0.3048)^3 cubic metres

Thus 214.62 cubic feet = 214.62 * (0.3048)^3 cubic metres
= 6.07736161557504 cubic metres
= 6 cubic metres, to one significant figure.

Answer 2

try converting feet into meters before plugging it into your formula...it will make things much easier!
