Question

You have an aquarium in the shape of a rectangular prism. The base is 4 feet by 2 feet. The height is 3 feet. How many square feet of glass were used to build the aquarium? (The top of the aquarium is open.)

Answer 1

4x2=8 then multiply it by 3 to find how much the aquarium can hold which would be 24 of how much water

Answer 2

Answer:

$44\ ft^{2}$

Step-by-step explanation:

we know that

The surface area of a rectangular prism with the top open  is equal to

$SA=B+Ph$

where

B is the area of the base of the prism

P is the perimeter of the base of the prism

h is the height of the prism

Find the area of the base B

$B=4*2=8\ ft^{2}$

Find the perimeter P

$B=2*(4+2)=12\ ft$

we have

$h=3\ ft$

substitute

$SA=8+(12)(3)=44\ ft^{2}$
