Question

an aquarium is 7dm long ,4dm wide and 5dm high. What is the area of the glass of which it is made?

Answer 1

Answer:

11000^2cm

Step-by-step explanation:

This question is not specific enough, so I can only answer what I think it is requesting which is the area surrounding the aquarium.

1 decimeter is ten centimeters or 3.937 inches.

40cm * 50cm = 2000cm^2cm (This is smaller face of the glass)

2000^2 cm* 2 = 4000cm^2cm (There are two small faces)

70cm * 50cm = 3500cm^2 (This is bigger face of the glass)

3500^2cm * 2 = 7000cm^2cm (There are two bigger faces)

4000 + 7000 = 11000^2cm (add them together)
