This question seems to me to be an exercise in applying the rule for a difference of squares in order to rewrite the difference of two relatively large numbers as the "simpler" product of other integers.

$175^2-124^2=(175-124)(175+124)=51\cdot299=15,249$

What is the volume of this rectangular

Basile [38]

<h3>Given:</h3>

l= 5 m
b= 4 m
h= 3 m

l= length
b= breadth
h= height

The volume of the given rectangular pyramid.

<h3>Solution:</h3>

$\large\boxed{Formula:V=\frac{1}{3}lbh}$

First, multiply the length (5), breadth (4) and height (3).

$5×4×3$

$= 60 \: cm$

Now, divide 60 by 3.

$\frac{60}{3}$

$\large\boxed{V= 20 \: {m}^{3}}$

<u>Therefore, the volume of the given rectangular pyramid is 20 cubic meters.</u>

A club has 10 members.

TEA [102]

That is the combination of 10 over 3, which is calculated as the quotient of factorials:
n!/k!(n-k)!
where n = 10 and k = 3:
= 10!/3!(10 - 3)!
= 10!/3!*7!
= (10*9*8)/(3*2*1)
= 720/6
= 120
therefore there a re 120 possible different groups
