Answer:

1. V = 729 m³
2. V = 512 in³
3. S = 7 ft
4. S = 7.12 cm
5. V = 94 in³
6. Difference of Volume of two box

• V = 78 cm³

Answer:

1.) 729m

know, volume of a cube = (side × side × side) cubic units.

Here, side = 9m.

Therefore, volume of a cube = 729 cubic m.

2.)  V = 512 in³

The formula for getting the volume of a cube is

V = S³ or

If the cube has a 8 in sides then

V = 8³ or 8×8×8

V = 512 in³

3.) 7 feet

The side of the cube with a volume of 343 cubic feet is 7 feet.

4.) 7.12 cm

Volume = side³

Side³ = 361 cm³

side = ∛361 cm

side = 7.12 cm

Answer: side = 7.12 cm

5.) The answer is 84in³

formula of rectangular

V= L x W x H

V= 3 x 4 x 7

V= 84

6.) 78  sqcm

volume of a cuboid box 1 = l*b*h

                                         = 4*5*6

                                         = 120

volume of a cuboid box 2 = l*b*h

                                         = 3*7*2

                                         = 42 sqcm

difference = 120-42

                = 78 sqcm
