Answer:
The width is 7 cm
Step-by-step explanation:
The volume of a cereal box is
V = l*w*h
6860 = 35 * w * 28
6860 =980 w
Divide each side by 980
6860/980 = w
7 = w
To find the area of a square picture with 16 inch sides, we must use the formula for the area of a square: A=s^2, where s represents the value of the side length of the square.
To solve, we must plug in the given side length of 16 inches into the formula.
A = (16 inches)^2
A= 256 inches^2
Therefore, your answer is 256 inches^2.
Hope this helps!
