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:Big Chungus
Step-by-step explanation:
You need to use the distance formula which is √(x2-x1)^2+(Y2-y1)^2
false
You shouldnt be cheating! what would your guardian say!!!
*edit*
<span>dont even need a protracter b/c there all evenly spaced and a line = 180 so 180 / 3 is 60</span>
This is the sum of cubes which factors to:
(x+2)(x^2-2x+4)
