Answer:
Step-by-step explanation:
As each step has the same depth and rise, they are respectively 1.2/4=0.3m and 1.8/4=0.45m.
Dividing the steps along the dotted lines, the total rise of the 4 concrete steps = (1+2+3+4)*0.45
= 4.5m
Total concrete volume = total rise * depth * width
= 4.5*0.3*1.8
= 2.43m^3
Answer:
Step-by-step explanation:
a much easier way - imagine there is another concrete stair exactly the same size and shape. flip it over n put it on top of this stair.
the pair will form a concrete block of 1.2m length, 1.8m width and (1.8+1.8/4)m height.
volume of the pair = 1.2*1.8*(1.8+1.8/4)
= 4.86m^3
so volume of concrete for 1 stair = 4.86/2 = 2.43m^3

Do 206/618 which is 0.3333333..
Move the decimal two places to the right.
Step-by-step explanation:
Simple interest =P (1+. R )^n
/100
Where P is the amount
R is rate (%)
n is number of years
So if you are given months your divide ➗ the number of months by 12 years
2710 *(1+ [ 3.8/100])^3/12
