A fish tank, in a shape of rectangular prism, measures

murzikaleks [220]

Answer:

The deep of the water would be 20 cm

Step-by-step explanation:

step 1

Find the volume of the water

The volume of the water is equal to

$V=LWH$

we have

$L=60\ cm\\W=40\ cm\\H=50/ cm$

substitute

$V=(60)(40)(50)$

$V=120,000\ cm^3$

step 2

Find the deep of the water, if the tank is returned to its horizontal position

(resting on its 60 cm × 100 cm base)

Now we have

$L=60\ cm\\W=100\ cm\\H=?\ cm$

$V=120,000\ cm^3$

substitute the given values

$120,000=(60)(100)H$

solve for H

$H=120,000/6,000$

$H=20\ cm$

therefore

The deep of the water would be 20 cm
