Question 2 of 7

A hospital has a large fish tank with the dimensions shown. The tank does NOT have a cover. What is the surface area of the fish tank?

Answer 1

2 times 8 x 12

192

2 times 5 x 8

80

2 times 12 x 5

60

192+80+60=332 ft^2

Answer 2

332 ft²

Explanation:

The total area of the fish tank is the sum of the areas of the base and the walls.

The area of a rectangle is A = side 1 × side 2

Base

A = 12 ft × 5 ft = 60 ft²

2 8×12-walls

A = 8 ft × 12 ft = 96 ft²

2 walls: 2 × 96 ft² = 192 ft²

2 5×8-walls

A = 5 ft × 8 ft = 40 ft²

2 walls: 2 × 40 ft² = 80 ft²

Total area: 60 ft² + 192 ft² + 80 ft² = 332 ft²
