The formula to find the volume of cube
cube = s^3
Therefore volume is equal to I^3
The second cube has 4x the First cube
4 × (I^3) = 4 ×I^3
Total volume of the second cube= 4I^3 cm3
Fact: the density(mass ÷ volume) of aluminium is 2.40g/cm3
Making mass the subject of the formula:
D = M ÷ V
(Times volume to remove deno minator)
Mass = Density × Volume
Mass = 2.40 × 4I ^3
Mass = 8.40I^3
By physics
weight= m × g
where
M = mass
g = acceleration due to gravity (= 9.8)
W = 8.40 I^3 × 9.8
Weight of aluminium = 82.32I^3

Answer:
6
Step-by-step explanation:
If c is 2 then that means you would multiply 2 and 3 to get 6
Answer:
6x+y=36
Step-by-step explanation:
6x - A rose is $6 and you do not know how many she will buy so you would put an "x" after that symbolizing how many she will buy.
y - Carnations cost $1 and the amount purchased is unknown so you would use "y". Because they cost 1 dollar, you will not need to add 1 in front of "y" because "y" by itself is already known as one variable.
36 - The total cost of the arrangement is ultimately going to be $36
