Step-by-step explanation:
The question is incomplete, as the options to select the required condition from were not listed. So, I will answer on general terms
From the question, we understand that the cube has an open-top and the surface ares is 256 in^2
Let L represents the edge length, the surface area (S) is:

Substitute 256 for S

Divide both sides by 5

Take square roots of both sides:


---- approximated
The volume of the cube is:




<em>So, the edge length of the cube is 7.16 inches and the volume is 366.36 cubic inches</em>

Answer:
Step-by-step explanation:
2y = 3 -2x
Rearrange the equation to slope-intercept form
y = -x + 3/2
Slope of line is 3/2.
Answer:
15 km/h
Step-by-step explanation:
Leo takes 15 minutes to cycle to school at an average speed of 12 km/h. What speed will he have if he only takes 12 minutes?
15 minutes * (1 hour)/(60 minutes) = 0.25 hour
speed = distance/time
distance = speed * time
distance = 12 km/h * 0.25 hour = 3 km
He cycles a distance of 3 km.
12 minutes * (1 hour)/(60 minutes) = 0.2 hour
speed = distance/time
speed = 3 km/(0.2 hour)
speed = 15 km/h
2 is the answer
Division is finding the number of times a number can be put into another number
