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

Re: conversion

im confused as what your trying to say wouldn't 1m^3 =1m^3??

Re: conversion

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

Start by converting 1 m to feet.

Re: conversion

Hi physicsgurl12!

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
