V= W × H × L
81000 = 30 × H × 45
81000 = 1350× H
81000/1350 = 1350/1350× H
H = 60 cm

<h3>How to determine the volume of the cone?</h3>
The volume of a cone is calculated using:

The parameters are not given.
So, we use the following assumed values
Radius, r = 5
Height, h =10
Using the assumed values, we have:

Evaluate the product

Hence, using the assumed values, the volume of the cone is

Answer:
Step-by-step explanation:
<u>Let the integers be x- 1, x and x +1, then:</u>
- x - 1 + x + x + 1 = 87
- 3x = 87
- x = 29
The integers are 28, 29, 30
I think you can do this way:
Volume = B*h where B is the area of the base.
B= 4 * 10 = 40
V= 40 * 15
V= 600 cm^3
