The volume of the first pyramid is 26 ftΒ³, corresponding to option A. The volume of the second pyramid is 144 inΒ³, also corresponding to option A.
; 1).
Given: Area of Base (B) = 6 ftΒ² and height (h) = 13 ft.
The volume of a pyramid can be calculated using the formula:
V o l u m e = 3 1 β Γ B a se A re a Γ h e i g h t
Substituting the values, we get:
V o l u m e = 3 1 β Γ 6 Γ 13
Calculating this:
V o l u m e = 3 1 β Γ 78 = 26 f t 3
Therefore, the answer for the first question is Option A: 26 ftΒ³.
2).
The base of the square pyramid has a side length of 6 inches. The height (h) of the pyramid is 12 inches.
First, we need to calculate the area of the base:
B a se A re a = s i d e Γ s i d e = 6 Γ 6 = 36 in c h e s 2
Now, we can calculate the volume using the same formula:
V o l u m e = 3 1 β Γ B a se A re a Γ h e i g h t
Substituting the values, we get:
V o l u m e = 3 1 β Γ 36 Γ 12
Calculating this:
V o l u m e = 3 1 β Γ 432 = 144 i n 3
Therefore, the answer for the second question is Option A: 144 inΒ³.

For example, if you have a pyramid with a base area of 12 ftΒ² and a height of 9 ft, you would calculate the volume as (1/3) * 12 * 9 = 36 ftΒ³.
The formula for the volume of a pyramid is derived from geometric principles and is consistent across various mathematical texts.
