Answer: first option

Step-by-step explanation:

The volume of a regular pyramid can be calculated with the following fromula:

V=\frac{B*h}{3}

Where B is the area of the base of the pyramid and h iis the height of the pyramid.

The base is a square, therefore, its area B is:

B=side^2\\B=(2units)^2\\B=4units

You know that the height is 3, therefore, you can substitute these values into the formula.

THerefore, the volume of the pyramid is:

V=\frac{4units^2*3units}{3}

V=4units^3

Find the distance travelled by Rubina if she takes 4 rounds of rectangular park whose length and breadth is 45m and 30m
ANTONII [103]
  • Length (l) = 45 m
  • Breadth (b) = 30 m
  • We know, perimeter of a rectangle = 2(length + breadth)
  • Therefore, perimeter of the rectangle
  • = 2(I + b)
  • = 2(45 + 30) m
  • = 2 × 75 m
  • = 150 m
  • So, the distance travelled by Rubina
  • = 4 × 150 m
  • = 600 m

<u>Answer:</u>

<em><u>The </u></em><em><u>distance </u></em><em><u>travelled</u></em><em><u> </u></em><em><u>by </u></em><em><u>Rubina </u></em><em><u>is </u></em><em><u>6</u></em><em><u>0</u></em><em><u>0</u></em><em><u> </u></em><em><u>m.</u></em>

Hope you could get an idea from here.
