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

7) (A) L x W x H

_________________________________________________

8) (C) S x S x S
