What is the volume of the pyramid?
k0ka [10]

Answer:

The volume of the rectangular pyramid is 80cm³

Step-by-step explanation:

To calculate the volume of a rectangular pyramid we have to use the following formula:

v = volume

w = width = 8 cm

l = length = 6 cm

h = height = 5 cm

v = (w * l * h) / 3

we replace the values that ​​we know        

v = (8cm * 6cm * 5 cm) / 3

v = 80cm³

The volume of the rectangular pyramid is 80cm³
