how do you find the surface area of a rectangular box with length 10 inches,width 6 inches and height 4 inches

1 answer:

4 0

SA = (Base Area • 2) + (Base Perimeter • Distance)

= (10*6 * 2) + (10 + 10 + 6 + 6 * 4)
= (60 * 2) + (32*4)
=120 + 128
SA = 248 inches squared

Compute the permutation.

Anon25 [30]

So you have 8 digits (number available) to form 3 digit numbers (number selected).

Using the formula $^{a} P_{c}$ where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.

The number of three digit numbers that can be formed = $^{8} P_{3}$
= 336

 O R

By using the formula $Permutation = \frac{a ! }{( a - c) !}$ where a is the number of available digits and c is the number of digits to be selected.

⇒ $Permutation = \frac{8 ! }{( 8 - 3) !}$

⇒ $Permutation = \frac{40, 320 }{120}$

⇒ Permutation = 336
