Answer:
Formula:
If the ratio of A and B is a ∶ b, assume A = ak and B = bk where k is a constant.
Calculation:
Let A, B and C be 5x, 8x and 10x respectively.
The difference between A and B = 27
⇒ 8x – 5x = 27
⇒ 3x = 27
⇒ x = 9
The number C = 10x
= 10 × 9
= 90
Ratio of 45 and C = 45 ∶ 90
= 1 ∶ 2
∴ The required ratio is 1 ∶ 2.

Step-by-step explanation:
1) Volume of rectangular prism = l x b x h
= 5 x 6 x 2
= 60 cm³
_________________________________________________
2) Volume of rectangular prism = l x b x h
= 6.5 x 6 x 5
= 6.5 x 30
= 195 cm³
_________________________________________________
3) Triple the length = 3 x length
height = 3 x 3
= 9 m
Volume of rectangular prism = l x b x h
= 3 x 4 x 9
= 108 m³

4) Volume of cube = a³
= 10³
= 1000 cm³
_________________________________________________
5) Volume of rectangular prism = l x b x h
= 5 x 8 x 10
= 400 m³
_________________________________________________
6) Volume of cube = a³
= 9³
= 729 cm³
