I am doing an MTO for work and need to calculate a swale concrete lining.
On
paper, easy. But I cannot get the formula to work on excel.

Obviously you have SQRT(number) and a couple of POWER(number) x thickness
x
length but I cannot get it to work.

The slope of the swale is 1.5 times the base, therefore you have 1.5 x b
squared + d squared and then this answer is sqrt x 2

=SQRT(1.5*B^2+d^2)*2

for both sides

don't understand this bit

+ b for total length x thickness x length.

nor this really, although it will end with *t*l
