1. A rectangular prism is 9 cm long, 7 cm wide, and 5 cm high. What is its volume?

Answer: 315 cm³

Solution:

In finding the volume of a rectangular prism using the formula V = length × width × height or V = lwh to get the answer.

  • [tex] \longrightarrow\rm{V = lwh}[/tex]
  • [tex] \longrightarrow\rm{V = (9cm)(7cm)(5cm)}[/tex]
  • [tex] \longrightarrow\rm{V = \green{315cm^3}}[/tex]

[tex]\therefore[/tex] the volume of a rectangular prism is 315cm³

2. A building is 16 m long and 9 m wide. it has a volume of 3,312m³. How tall is the building?

Answer: 23m

Solution:

Multiply the length and width then divide it by the volume to get the answer.

  • [tex] \longrightarrow \rm{h = \frac{length \times width}{volume}}[/tex]
  • [tex] \longrightarrow \rm{h = \frac{16m \times 9m}{3312m^3}}[/tex]
  • [tex] \longrightarrow \rm{h = \frac{144m}{3312m^3}}[/tex]
  • [tex] \longrightarrow \rm{h = \green{23m}}[/tex]

[tex]\therefore[/tex] the building is 23 m long.

To check

  • [tex] \longrightarrow \rm{V = lwh}[/tex]
  • [tex] \longrightarrow \rm{V = (16m)(9m)(23m)}[/tex]
  • [tex] \longrightarrow \rm{V = \green{3312m^3}}[/tex]

Thus, the answer is correct!

3. Look for a rectangular prism around you. Get a tape measure or a ruler to measure its length, width, height.

a. (kindly check the photo above!)

b. Do you think this item will fit in a box that is 20 cm long, 20 cm wide, 50 cm tall? Why or why not?

  • Yes! because, the rectangular speaker is 7 cm long, 5 cm wide, and 4 cm high.
