What is the surface area of the present?

1,350

Step-by-step explanation:

To find Surface Area you need to area of all the sides and add them

So to find one side of the cube you do L x H

So 15 x 15 = 225

Since all the sides of the cube are the same, you don't need to figure out the area of the other sides.

225 x 6 sides = 1,350

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
