To find the height of the oblique triangular pyramid, you can use the formula for the volume of a pyramid:
[
V = frac{1}{3} times text{Base Area} times text{Height}
]
Where:
– ( V ) is the volume,
– Base Area is the area of the base,
– Height is the height of the pyramid.
Given:
– Volume (( V )) = 35 cubic units,
– Base Area = 21 square units.
Now, plug in the values:
[
35 = frac{1}{3} times 21 times text{Height}
]
To isolate Height, first multiply both sides by 3:
[
105 = 21 times text{Height}
]
Now, divide both sides by 21:
[
text{Height} = frac{105}{21} = 5
]
So, the height of the pyramid is:
5 units.
