Question

guys please help :((

Answer 1

A cubic ice cube weighs 920 grams. If the density of ice is .92g/cm^3, then at least how many sucj ice cubes would it take o build a towr that is three meters tall? there are 100cm in a meter.
A) 23
B) 21
C) 25
D) 30
E) 34

Answer 2

density = mass/volume. use the density and mass to find the volume of an ice cube.
the length of one side of a cube is length^3, so find the cubic root.
3*100cm/(length of one cube) = how many ice cubes to build the tower

Answer 3

Knowing that there are .92grams of ice in a cubic centimeter, we can calculate the size of the ice cube.
\[920\div.92\]
That gives us 1000 cubic centimeters in the 920 gram ice cube from the equation
\[Density = Mass \div Volume\]
Knowing that it is a cube it must have equal sides so we take the cube root of 1000 to find the height of the cube.
\[\sqrt[3]{1000} = 10cm\]
Now we know that each cube is 10cm high, which means we need 10 of them to make the 100cm tower

Answer 4

but they want it in meter

Answer 5

Alright then, if each cube is 10cm and you want it to be 3 meters tall ie 300cm then you need 30 of them

Answer 6

Answer D

thank you very much :)
