This cube has 6 faces, and all side lengths are equal.
The volume of a cube with sides of length L is given by L^3.
The problem says that the volume is 7^3, which means that each side is 7
The surface area of a cube of length L is 6*L^2. Since L = 7, the surface area is:
6*7^2 = 6*49 = 294 cm^2
Each student got 9 pencils. Since 78/8= 9.75 you would round down since a student can't have 3/4th of a pencil.
y=undefinedx
Explained: This one is rather hard since there's no y-Intercept and the slope is undefined. I tried my best.

Answer:30km/hr
Step-by-step explanation:
Total distance=294km
Speed=s
Distance=d
Time=t
First drive:
t=5
d=s x t
d=s x 5
d=5s
Second drive:
t=4
Speed is 6km/h greater than the first speed
The new speed= s+6
d=4(s+6)
Total distance=294
5s + 4(s + 6)=294
5s + 4s + 24=294
Collect like terms
5s + 4s=294 - 24
9s=270
Divide both sides by 9
9s/9=270/9
s=30
First speed=30km/hr
