Answer 1

a) Volume of rectangular container:

1 foot = 12 inches

`\begin{gathered} V=\text{tall}* long* wide \\ V=12*4*2.5 \\ V=120inches^3 \end{gathered}`

b) Volume of the cylindrical container:

c) First, we convert the volumes of the containers into the same units.

For volume of the rectangular container in centimeters:

1 inch3 = 16.3871 cm3

With this, we can say that the rectangular container has a larger volume than the cylindrical container. Therefore, the cylindrical container is a better buy.

Answer:

a) V = 120 in^3

b) V = 1907.55 cm^3
