Answer:

Estimate the surface area of a cube with side length 9.9 in.

A) 100 in²  

B) 400 in²  

C) 600 in²

D) 1000 in²

Step-by-step explanation:

9.9 to the nearest whole number is 10

We know the side length of the cube is 10

We work out the area of face and multiply by 6.

10 x 10 = 100

100 x 6 = 600 in²

Answer:

600 is the answer

Step-by-step explanation:

We can round each side length to 10 in. Therefore, the area of one face is 100 in2. Since there are 6 congruent faces in a cube, the total estimated surface area of 600 in2.

Alright

so the first thing you do is set up your equation


it should look something like this:


90=3x+10

next, you subtract 10 from each side resulting in 80

3x=80

divide 80 by three and you should get 26.67 or rounding either 26 or 27

then round up or down... according to the instructions.....

hope I could help! :)) XD
