Nikita built a dollhouse in the shape of a rectangular prism. the base of the dollhouse has an area of 12 square feet. if the volume of the dollhouse is 48ft3, what is the height of the dollhouse?

Volume= (area of the base) x height

Or length x width x height.

In this case you would plug in 48 for the volume and 12 for the area, so your equation would be

12x=48

Divide 12 from both sides of the equal sign and your answer is 4

Step-by-step explanation:Volume= (area of the base) x height

Or length x width x height.

In this case you would plug in 48 for the volume and 12 for the area, so your equation would be

12x=48

Divide 12 from both sides of the equal sign and your answer is 4

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
