7.5 days

Step-by-step explanation:

You can build a doghouse in 6 hours.

It will take time to build 10 doghouses = 10 × 6

                                                               = 60 hours.

If you work 8 hours per day, you will work 60 hours =

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
