Answer:
90ml
Step-by-step explanation:
all we need to do is find 60% of 150
60% of 150 is 90
The surface area formula for a cube is: 6 * s^2, where s is the side length.
The two surface areas are:
6 * 3^2 = 54
and
6 * 8^2 = 384
The ratio of their surface areas, from the surface area of the smaller cube to the surface area of the larger cube is:
54/384 = 9/64
The answer is 9/64.
Note that another way to to find the ratio of the squares of the side lengths of the cubes.
I think the answer is 7.725 so sorry if I’m wrong but see if that answer is correct
