Answer 1

\[=\frac{ 1 }{ 2 }\times160\]\[=?\]

Answer 2

80

Answer 3

yep :)

Answer 4

that the answer?

Answer 5

yes

Answer 6

thx

Answer 7

Answer 8

The scale factor tells you how much each side is scaled by. The volume of a cube is given by
\[\text{Vol} = L \times W \times H\]
What if we scale each side by 1/2 (we multiply each side by 1/2)?
\[\text{Vol} = \frac{1}{2}L \times \frac{1}{2}W \times \frac{1}{2}H = \frac{1}{8} \left(L \times W \times H \right)\]
Which suggests that scaling the figure by a factor of 1/2 will result in multiplying the volume by 1/8.

Answer 9

they got the same answer as you did
