Answer:
yes they form a proportion
Step-by-step explanation:
1 to 3 and 7 to 21 are equal
we can check this by multiplying each number in the 1 to 3 ratio by 7 to make it equal with the other ratio, 7 to 21.
(sorry if this is confusing but I hope it helped)
cuboid=3*3*5 [i.e l*b*h]
LCM of 3,5=15
i.e 15cm is the dimension of the final cube.
therefore cuboid required across length=15/3=5
similarly, across breadth=15/3=5
similarly, across height=15/5=3
Therefore total no of cuboid=5*5*3=75
The final balance is $580.81.
The total compound interest is $80.81.
