Question

The surface area is 445.5cm2. Calculate the value of p. (don't spam)
With explanation please

Answer 1

Answer:

4.5

Step-by-step explanation:

Given,

Total Surface Area = 445.5

There will be 3 different combination of surface which then will be repeated.

Different combination of surface,

Surface 1 : (p,2p) Area = 2$p^{2}$

Surface 2 : (p,3p) Area = 3$p^{2}$

Surface 3 : (3p,2p) Area = 6$p^{2}$

Therefore TSA = 2 ( 2+3+6)$p^{2}$

=>2(11)$p^{2}$ = 445.5

=> $p^{2}$ = 20.25

=> p = 4.5
