The Deep Dive
To find the volume of a triangular pyramid (also known as a tetrahedron), you can use the formula: \[ \text{Volume} = \frac{1}{3} \times \text{Base Area} \times \text{Height} \] First, we need to calculate the area of its triangular base. The base area \( A \) of a triangle is given by: \[ A = \frac{1}{2} \times \text{Base length} \times \text{Base height} \] Here, the base length is 9 inches, and the base height is 10 inches: \[ A = \frac{1}{2} \times 9 \times 10 = 45 \, \text{square inches} \] Now we have the base area. Next, we multiply this by the height of the pyramid (which is 32 inches): \[ \text{Volume} = \frac{1}{3} \times 45 \times 32 \] Calculating that gives: \[ \text{Volume} = \frac{1}{3} \times 1440 = 480 \, \text{cubic inches} \] So, the volume of the triangular pyramid is **480 cubic inches**.
