Answer 2

The aquarium can be made by 83 sq. ft. of glass.

Explanation:

The public library aquarium is in the shape of a hollow cuboid.

The dimensions of the hollow cuboid are 6 ft by 2.5 ft. by 4 ft.

Now, the total surface area of the aquarium will be given by 2(LW + WH + HL)

Where, L = length = 6 ft, W = width = 2.5 ft and H = height = 4 ft.

If the top of the aquarium is open, then the total surface area will be

= 2(WH + HL) + LW

= 2(2.5 × 4 + 4 × 6) + 6 × 2.5

= 83 sq. ft.

Therefore, the aquarium can be made by 83 sq. ft. of glass. (Answer)
