Hello po,I need this tommorow po.

Question number 1.Ana has a toy box about l=20m,w=15m and l=30m.What is the volume?

Question number 2. Dina has a triangle about b=18cm and h=15cm.What is the area?

-with step by step explanation po.
correct and understanding explanation-brainliest

VOLUME & AREA

Answer:

  1. 9, 000 m³
  2. 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.
