Answer:
Esma can fit 3 packages in the box because 20+10+10=30 and 5+2+2=9 so if you add up 9 three times you get 27 and that is the closest number you can get before going over.
Step-by-step explanation:
Let's imagine we enclosed the entire shape in a 15 inch wide, 21 inch tall rectangle, area 315 sq inches.
From that rectangle we have to take away the 3x6 bottom left corner, and a strip 21-6=15 inches long and 3 inches wide on the right.
A = 15×21 - 3×6 - 3×15 = 315 - 63 = 252 sq in
Answer: D. 252 inches squared, last choice
Answer:
The correct answer is s³/6
Step-by-step explanation:
<u>Points to remember</u>
Volume of pyramid = (a²h)/3
Where a - side of base
h - height of pyramid
It is given that, a pyramid has a square base with sides of length s the height of The pyramid is equal to 1/2 Of the length of a side on the base
<u>To find the formula:-</u>
Here side length a = s and
height h = 1/2(s) = s/2
Volume = (a²h)/3
= (s² * s/2)/3
= s³/6
The correct answer is s³/6
