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 to draw a net.

Volume: 45000cm^3

Surface area: 6600cm^2

Step-by-step 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

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
