Question

This composite figure is made of two identical pyramids

Answer 1

Question:

This composite figure is made of two identical pyramids attached at their bases. Each pyramid has a height of 2 units.

~2, 5, 0.25

Which expression represents the volume, in cubic units, of the composite figure?

Answer:

The expression that represents the volume of the pyramid is  2(1/3(5)(0.25)(2))

Step-by-step explanation:

Here we volume of pyramid given by the following expression;

$Volume \ of \ pyramid, V = \frac{lwh}{3}$

Where:

l = Length of base = 5

w = Width of base = 0.25

h = Height of pyramid = 2

Given that the dimensions are l = 5, w = 0.25 and h = 2 where we have two pyramids, the total volume becomes;

$2 \times Volume \ of \ pyramid, V = 2 \times \frac{lwh}{3} = 2 \times \frac{5 \times 0.25 \times 2}{3} = 2(1/3(5)(0.25)(2))$

The expression that represents the volume of the pyramid = 2(1/3(5)(0.25)(2)).
