Question

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!

The new middle school aquarium is a rectangular prism with these dimensions:

Length: 60 cm
Width: 25cm
Height: 30 cm

Find how much water it will take to fill the aquarium to the top (volume).

Find how much glass it will take to make the aquarium (surface area).

Note: There is no “top” to the aquarium. It may help to draw a net.

Answer 1

Volume: 45000cm^3

Surface area: 6600cm^2

Explanation:

The volume is all the side lengths multiplied, so 60*25*30 = 45,000 cm^3.

Now let's calculate the surface area.

The bottom is the width * the length, or 60*25 cm^2.

One of the sides is the length * the height, or 60*30 cm^2. This is multiplied by 2 because there are 2 of those sides.

The other pair of sides is the width * the height, or 25*30 cm^2, again multiplied by 2.

In total, the surface area is

60*25+2*60*30+2*25*30 = 6600cm^2
