Answer:

#(0.41)^3" "=" "0.068921#

Explanation:

If you have a calculator it is as easy as pressing buttons. If not then by manual methods we have:

#color(purple)("This is a sort of cheat way that gets round the decimal point")#
Breaking this down into parts

#0.41 = 41/100 -> (0.41)^3 =(41/100)^3#

#(41)^3xx(1/100)^3=(41)^3xx1/1000000#

Cubing the 41

#" "41#
#ul(" "41) larr" multiply"#
#" "1640#
#ul(" "41) larr" add"#
#" "1681#
#ul(" "41) larr" multiply"#
#" "67240#
#ul(" "1681) larr" add"#
#" "68921#

Putting it all together:

#68921xx1/1000000 = 0.068921#
