VOLUME & AREA
Answer:
- 9, 000 m³
- 135 cm²
Step-by-step explanation:
For number one question, the formula to be used in finding the volume of a box is:
- [tex] \sf V = (l)(w)(h)[/tex]
Plug in all the given to the formula then, solve:
- [tex] \sf V = (l)(w)(h)[/tex]
- [tex] \sf V = (20)(15)(30)[/tex]
- [tex] \sf V = (300)(30)[/tex]
- [tex] \sf V = 9,000 \: m {}^{3} [/tex]
Therefore, the volume of a toy box is 9, 000 cubic meters.
For question number two, in finding the area of triangle which express by base and height, the formula to be used is:
- [tex] \sf A = \frac{1}{2} (b)(h)[/tex]
Plug in all the given to the formula then, solve:
- [tex] \sf A = \frac{1}{2} (b)(h)[/tex]
- [tex] \sf A = \frac{1}{2} (18)(15)[/tex]
- [tex] \sf A = \frac{1}{2} (270)[/tex]
- [tex] \sf A= 135 \: cm {}^{2} [/tex]
Therefore, the area of Dina's triangle is 135 square centimeters.
