Question

How much glass in square cm is needed for an aquarium (without a glass lid) that is 100 cm deep, 400 cm long, and 200 cm wide?

Answer 1

Answer:

Step-by-step explanation:

There are two possible answers for this question.

If the aquarium has a glass lid, more glass will be needed

If the aquarium has no glass lid (like normal) less glass will be needed.

To find the two solutions find the area of each side. Because the sides are paired, you only have to calculate the area 3 times.

We start with the sides200cm*600cm=120000cm squared*2 =240000cm squared

the small sides

200cm*300cm=60000cm*2= 120000cm squared

and the top and bottom

300cm*600cm= 180000cm....

with no glass lid the amount of glass needed is 540000cm squared

with a glass lid the amount of glass needed is 720000cm squared
