U would multiply the number on the side and the number on the bottom. hope that helps :)
Answer:
Step-by-step explanation:
The volume of a cube is
V=s^3, we are told the volume is 10u^3 and that it will be filled with cubes having a side of 1/2 so
n(1/2)^3=10, where n will be the number of these small cubes
n(1/8)=10 upon multiplying each side by 8
n=80
So it will take 80 cubes of side length 1/2 to have a volume equal to 10u^3
New price is 1.05 because if you multiply 1.50 by .30 then your answer is 45. subtract 45 from 1.50 you get 1.05
