PLEASE HELP!!!! TIMED EXAM
alexandr402 [8]

Answer:

The correct option is V = one-third (6) (4) (8).

Step-by-step explanation:

The volume of a rectangular pyramid is:

V=\frac{1}{3}\ l\times b\times h

Here,

V = volume

l = length

b = base

h = height

The information provided is:

l = 6 inches

b = 4 inches

h = 8 inches.

Compute the equation of the volume of a rectangular pyramid as follows:

V=\frac{1}{3}\ l\times b\times h

   =\frac{1}{3}\times 6\times 4\times 8

Thus, the correct option is V = one-third (6) (4) (8).
