Answer 1

Question :-

• If there are X rows of chairs and each row contains 3 times the square of number of rows of chairs, determinethe total number of chairs.

Answer :-

$\implies \bf {3x}^{3}$

Given :-

• Total number of rows = X rows

• Number of chair contain in each row = 3 times the square of number of rows.

To find :-

• Total number of chairs.

Solution :-

Number of rows = x

Number of chair in each row = $\bf {3x}^{2}$

Thus ,

The total number of chairs = Number of rows × number of chairs in each row

$\implies \bf \: x \times {3} x^{2}$

$\\ \implies \bf {3}x^{3}$
