Solution:
Given,
Volume of the-
First cube box=1728 in³
Second cube box=13824in³
We know that volume of cube =a³
So for the first box
a³= 1728 in³
a= 12 in
Now, surface area of the first box
6a²= 6×(12)²
= 864 in²
and for the second box
b³= 13824 in³
b= 24 in
Now, the surface area of the second box
6b²= 6×(24)²
= 3456 in²
Now, the ratio of the surface area of first box to the second box will be
864:3456
=1:4
The surface area of the larger of two boxes is
3456 in²
Answer:
67 square units
Step-by-step explanation:
Circumference/pi = diameter
29/3.14 = 9.24
Radius = 9.24/2 = 4.62
A = pi * r^2
A = 3.14 * 4.62^2 = 67 square units
