I would add, the weight of the backpack and the weight of the school books which is 28.36.
So Rico's backpack altogether weighs 28.36.
I'm pretty sure.
Answer:

Step-by-step explanation:
Find the GCF of the numbers 48, 6 and 26.
The largest number each can be divided by is 2, which is the GCF.
Find the GCF of 
The GCF is always the smallest exponent, so
is the GCF
Combine the two GCF for the answer

Answer:
or 
Step-by-step explanation:
The formula for volume is Base * Height * Width; and the formula for area is Base * Height.
This problem mentions the structure is a cube and therefore it is assumed that every wall has the same area. Since there are 6 sides to a cube you divide the total amount of ft which make up this cube to know the area to each wall.
= 2.25 or
per wall
With the area of each wall you can find the base and height:
base * height = area

base =
m
height =
m
since: base=height=width, the width also equals
m
volume =
=
