Answer:
a 120 cm^3
b 70 cm^3
Step-by-step explanation:
The volume of a right rectangular prism is given by
V = l*w*h
10 a V = 12*2*5
=120 cm^3
10 b V = 2.5 *8 *3.5
=70 cm^3

Answer:
a. 10
b. 5
c. 3 with 1/4 pound left over
Step-by-step explanation:
You can find the number of 1/4 pound bags by dividing 2 1/2 pounds by 1/4 pound. In decimal, this is obvious:
2.5/0.25 = 10
Using fractions, it is ...
(2 1/2)/(1/4) = (5/2)/(1/4) = (10/4)/(1/4) = 10/1 = 10
__
a) Tim can make 10 1/4-pound bags from 2 1/2 pounds.
__
b) It is worthwhile to note that a 1/2-pound bag is equivalent to two 1/4-pound bags. So, the number of 1/2-pound bags will be 10/2 = 5.
Tim can make 5 1/2-pound bags from 2 1/2 pounds.
__
c) It is worthwhile to note that a 3/4-pound bag is equivalent to three 1/4-pound bags. So, the number of 3/4-pound bags will be 10/3 = 3 1/3.
Tim can make 3 3/4-pound bags from 2 1/2 pounds, with 1/4 pound left over.
