sqrt(54) = sqrt (9 x 6) = 3 sqrt 6 = 3 x 2.4495 = 7.348
3/8 x 20 = 3/8 x 20/1 = (3x20)/(8x1) = 60/8 = 7 1/2
Do you have a programmable handheld calculator? They are easy to get these days...I even had one many years ago...
There IS a calculator on this site that would give you this answer very quickly and easily.....
45^2 = 45 x 45 =2025
5a = . ; Divide both sides by 5
a= (. ;)/5

SORRY Folks ! I thought the equation I had was a = area , but in that equation a= length of one side of the base......
Apologies ! Thanx oldeng and geno !!
PROFIT is bigger on woodchipper AND the TIME is LESS.....Use all of the time to make chippers!
Oldeng...
Yah, that is true for a TRIANGULAR pyramid only...
...question asked about a PENTAGONAL pyramid.....hence the different formula.
8^(1/3) = \(\sqrt[3]{8}\) = 2
