Answer:

1. How much soil is needed to fill a pit that is 5 m deep, 3 m wide, and 10 m long?

l = 10 m
w = 3 m
h = 5 m

V = l x w x h = 10 x 3 x 5 = 150 cm³

2. A swimming pool measures 12 m long, 8 m wide, and 6 m high. How much water does it hold?

l = 12 m
w = 8 m
h = 6 m

V = l x w x h = 12 x 8 x 6 = 576 cm³

3. A Rubik’s cube has a volume of 512 cm3 . What is its side?

All sides of a Rubik's cube are congruent, meaning they are equal. Due to the face that each sides of the Rubik's cube is square in shape.

So,

Since l = w = h, then we need to divide the total by 3.

V/3 = side

512 cm³/3 = side

side = 170.67 cm

4. Myra bought a rectangular-shaped jar with a length of 120 cm, a width of 80 cm, and a height of 100 cm. how much water is needed to fill the jar?

l = 120 cm
w = 80 cm
h = 100 cm

V = l x w x h = 120 x 80 x 100 = 960,000 cm³

5. What is the difference between the volume of a box whose dimensions are 11 cm x 14 cm x 8 cm and 4 cm x 9 cm x 5 cm?

To determine the difference between the volume of a box whose dimensions are 11 cm x 14 cm x 8 cm and 4 cm x 9 cm x 5 cm. Let box A = 11 cm x 14 cm x 8 cm and box B = 4 cm x 9 cm x 5 cm

Calculate them separately:

box A

= 11 cm x 14 cm x 8 cm

= 1232 cm³

box B
= 4 cm x 9 cm x 5 cm
= 180 cm³

So, the difference between the volume of a box whose dimensions are 11 cm x 14 cm x 8 cm and 4 cm x 9 cm x 5 cm is that the first box has a larger volume comapred to the second box.
