QuestionFind the volume of Lin's aquarium with dimensions 72ft\frac{7}{2} \mathrm{ft} (length), 43ft\frac{4}{3} \mathrm{ft} (width), and 32ft\frac{3}{2} \mathrm{ft} (height).

STEP 1

Assumptions1. The length of the aquarium is 7ft\frac{7}{} \mathrm{ft} . The width of the aquarium is 43ft\frac{4}{3} \mathrm{ft}
3. The height of the aquarium is 3ft\frac{3}{} \mathrm{ft}
4. The volume of a rectangular prism (which is the shape of the aquarium) is calculated by multiplying the length, width, and height.

STEP 2

We need to find the volume of the aquarium. We can do this by multiplying the length, width, and height.
Volume=Length×Width×HeightVolume = Length \times Width \times Height

STEP 3

Now, plug in the given values for the length, width, and height to calculate the volume.
Volume=72ft×3ft×32ftVolume = \frac{7}{2} \mathrm{ft} \times \frac{}{3} \mathrm{ft} \times \frac{3}{2} \mathrm{ft}

STEP 4

First, multiply the fractions 72\frac{7}{2} and 43\frac{4}{3}.
72×43=7×42×3=286\frac{7}{2} \times \frac{4}{3} = \frac{7 \times4}{2 \times3} = \frac{28}{6}

STEP 5

implify the fraction 28\frac{28}{} to get the intermediate volume.
28=143ft2\frac{28}{} = \frac{14}{3} \mathrm{ft}^2

STEP 6

Now, multiply the intermediate volume 143ft2\frac{14}{3} \mathrm{ft}^2 with the height 32ft\frac{3}{2} \mathrm{ft} to get the volume of the aquarium.
Volume=143ft2×32ftVolume = \frac{14}{3} \mathrm{ft}^2 \times \frac{3}{2} \mathrm{ft}

STEP 7

Multiply the fractions 143\frac{14}{3} and 32\frac{3}{2}.
143×32=14×33×2=426ft3\frac{14}{3} \times \frac{3}{2} = \frac{14 \times3}{3 \times2} = \frac{42}{6} \mathrm{ft}^3

STEP 8

implify the fraction 426\frac{42}{6} to get the volume of the aquarium.
Volume=426=7ft3Volume = \frac{42}{6} =7 \mathrm{ft}^3The volume of Lin's second aquarium is 7ft37 \mathrm{ft}^3.
