Answer:
Step-by-step explanation:
The volume of a triangular pyramid can be found using the following formula:
Basically, we have to multiply 1/3, the height, and the base area.
We know that the base area is 8.2 square centimeters and the height is 4 centimeters.
Substitute the values into the formula.
Multiply 8.2 square centimeters and 4 centimeters.
- 8.2 cm² * 4 cm= 32.8 cm³
Multiply 1/3 and 32.8 cubic centimeters.
Round to the nearest tenth.
The 3 in the hundredth place tells us to leave the 9 in the tenth place.
The volume of the triangle pyramid is about 10.9 cubic centimeters.
