Question

Calculate the volume of a triangular pyramid 12cm tall and with a base 12cm long and 10cm wide

Answer 1

Remember that the volume of a triangular pyramid can be calculated using the formula:

$V=\frac{A_{base}\cdot height}{3}$

So first, let's calculate the area of the base:

$A_{base}=\frac{10\cdot12}{2}=60$

Using this in the formula,

$V=\frac{60\cdot12}{3}=240$

Thereby, the volume of the pyramid is 240 cubic centimiters
