Answer:
B. 
Step-by-step explanation:
Given,
The number of smaller cubes = 
So, the number of cubes that have no coloured faces. =
,
Note : If a cube painted outside having side n is split into n³ cubes, then the volume volume that is not painted = (n-2)³
Thus, the remaining cubes that have been painted red on at least one of their faces
= Total cubes - cubes with no painted face



Hence, OPTION B is correct.
Answer:
1. V = 37.7
2. V =603.19
Step-by-step explanation:
1. V = (3.14)×3^2 4/3
V =37.7
2. V=(3.14)×(3×4)^2 4/3
V = (3.14)×12^2 4/3
V = 603.19
Answer:
G = 0.75s
Step-by-step explanation:
First find the unit rate: How many gallons of water can be pumped in 1 second. This means you just have to divide by however many seconds it is being pumped. I'm using 12 and 9. 9/12 = 0.75. This means that in 1 second 0.75 or 3/4 of a gallon will be pumped. Therefore:
G = 0.75s
