10. The volume of a reservoir is 30m3. What is the height of the reservoir if the length and width of the base is 2,5m and 4m?
A. 3m B. 48m C. 4.6 m
To find the height of the reservoir, we can use the formula for volume of a rectangular prism, which is length times width times height.
Given:
Volume = 30m^3
Length = 2.5m
Width = 4m
Using the formula:
30m^3 = 2.5m * 4m * height
To solve for height, divide both sides of the equation by (2.5m * 4m):
height = 30m^3 / (2.5m * 4m)
height = 30m^3 / 10m^2
height = 3m
So the height of the reservoir is 3m. Therefore, the answer is A. 3m.
To find the height of the reservoir, we can use the formula for the volume of a rectangular prism: volume = length * width * height.
Given:
Volume = 30m^3
Length = 2.5m
Width = 4m
Let's assume the height of the reservoir is h.
Substituting the given values into the formula, we can solve for h:
30m^3 = 2.5m * 4m * h
Dividing both sides of the equation by 2.5m * 4m:
30m^3 / (2.5m * 4m) = h
Simplifying:
30m^3 / (10m^2) = h
Simplifying further:
3m = h
Therefore, the height of the reservoir is 3 meters.
The answer is A. 3m.
