Question

Need help with finding answer

Answer 1

The correct answer is option 3. volume of Pyramid=2520 cm³

Explanation:

Formula:

Volume of triangular pyramid is 1/3 *(Base area * Height)

Area of triangle = 1/2(Base * Height)

To find Base area of base triangle

Base b = 18 cm

Height = 24 cm

Area A = 1/2(Base * Height) = 1/2(18*24) = 216 cm²

To find the volume of pyramid

Base area = 216 cm² and height = 35 cm

Volume V = 1/3 *(Base area * Height)

V = 1/3(216*35) = 2520 cm³

Therefore option 3 is the correct answer

Answer 2

Answer: 2520 cm³

Explanation:

1. You must use the following formula for calculate the volume of a triangular pyramid, which is:

`V=(B*h)/(3)`

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

2. Calculate the area of the triangular base:

`B=(24cm*18cm)/(2)\\B=216cm^(2)`

3. Susbstiute values into the formula for calculate the volume. Then, you obtain the following result:

`V=(216cm^(2)*35cm)/(3)=2520cm^(3)`
