Answer:
729m³
Step-by-step explanation:
To find the length of one side find the cube root of 1728m³
³√1728=12metres
To find the length of the smaller cube
ratio 3:4.
4/7=12m
3/7=?
<u>3</u><u>/</u><u>7</u><u>×</u><u>1</u><u>2</u><u> </u>= 3/7×12×7/4
<u> </u><u> </u><u> </u>4/7
=9metres
To find volume of the small cube
volume=9×9×9
=729m³
Answer:
x = 10
y = 5
Step-by-step explanation:
Let the two numbers be x and y
Difference between the two is 10
x-y = 10
Sum;
x+ y is four times the smallest number
Let the smaller number be y
x+ y = 4y
Subtracting equation ii from i
-2y = 10 -4y
4y-2y = 10
2y = 10
y = 10/2
y = 5
Recall;
x-y = 10
x = 10 + y
x = 10 + 5 = 15
