Answer:
Step-by-step explanation:
ok so...
1 ) To find the volume of the old locker-->
volume of a cuboid=l*b*h
so, volume= 3*3*6
volume=54ft^3
2) Now the old locker-->
volume of a cuboid=l*b*h (We apply the same formula)
lets multiply the height and the breadth first coz they're in mixed fractions->
2 1/2 * 5 1/2 [however we need to convert this into improper fraction first]
here are steps to convert mixed fractions to improper fractions-
Multiply the whole number part by the fraction's denominator.
Add that value to the numerator.
Then write the result on top of the denominator. (the denominator stays the same)
5/2*11/2= 55/4
now we can multiply this value to the length (coz till now we only did b*h)
55/4*4/1 [remember that there is always an imaginary 1 existing under no.s]
v=220/4 we can convert this into a whole no. by divison [just divide]
so the volume= 55ft^3
3) We can easily compare which no. is bigger...
55 or 54...well ys the ans is 55 so the old locker has more storage
space.
