8 0

Answer:

0 and -3

Step-by-step explanation:

Natural numbers are all whole numbers from 1 to infinity. i.e

1, 2, 3, 4 . . .

These numbers do not include 0.

Integers are all whole numbers (positive and negative) including 0. i.e

. . ., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, . . .

These numbers are all natural numbers including their negative counterparts (i.e negatives of the natural numbers) and also 0.

<em>So from the options in the question:</em>

1 is a natural number as well as an integer

-5.41 is not a natural number neither is it an integer.

3 root 12 (written as 3\sqrt{12}) is neither a natural nor an integer number.

0 is an integer but not a natural number

-3 is an integer but not a natural number

-9/7 is neither a natural nor an integer number.

23 is a natural number as well as an integer

Therefore, 0 and -3 are integers but not natural numbers

puteri [66]

Answer:

volume = 13500 cm^{3}

Step-by-step explanation:

For a given pyramid, its volume can be determined by:

volume of pyramid = \frac{lwh}{3}

Where: l is the base length, w is the base width and h id the height of the pyramid.

For the given question, l 30 cm, w = 30 cm and h = 45 cm.

So that,

volume = \frac{30*30*45}{3}

            = \frac{40500}{3}

            = 13500

volume = 13500 cm^{3}

The volume of the pyramid is 13500 cm^{3}.
