Volume in meters to feet

  1. Sep 25, 2011 #1
    1. The problem statement, all variables and given/known data
    A bin has a volume of 1.5m^3 The volume in feet is closest to
    a, 35
    b, 47
    c, 41
    d, 59
    e, 53

    2. Relevant equations

    1m=100cm 1in=2.54cm 1ft=12in

    3. The attempt at a solution
    i know a is wrong

    1.5m= 150 cm /2.54= 59in/ 12 inches=4.9 ft ??

    Re: conversion

    You converted a distance from meters to feet, but what you need to convert is a volume in meters3 to feet3.

    Think this way:
    1 m3 = (m)3 = (?ft)3 = (?)3 ft3

    Well, sure. What you want is 1 m3 = x ft3.

    Start by converting 1 m to feet.

    Hi physicsgurl12! :smile:

    You need to treat the third power separately from the value 1.5.

    So:
    1.5 m3 = 1.5 x (1 m)3 = 1.5 x (100 cm)3 = 1.5 x (100 / 2.54 inch)3 = 1.5 x (100 / 2.54 / 12 ft)3
