Answer:
top rectangular prism = .6 x .4 x 2.4
middle rectangular prism = .6 x .8 x 2.4
bottom rectangular prism = .6 x 1.2 x 2.4
concrete needed = 3.672 cubic meters
Step-by-step explanation:
The steps can be broken into bottom step from front to back, middle step from front to back, top step from front to back resulting in
three rectangles
The dimensions of each solid figure can be found since we know the steps are equal so we divide the height and width by 3 equal parts and the length stays the same. So...
1.8/3=.6 m
1.2/3=.4 m
top rectangular prism = .6 x .4 x 2.4
middle rectangular prism = .6 x .8 x 2.4
bottom rectangular prism = .6 x 1.2 x 2.4
Find the volume by plugging our dimensions into the formula for volume for each step and then add all three steps together for total volume...
.6 x .4 x 2.4= .576
.6 x .8 x 2.4= 1.152
.6 x 1.2 x 2.4=1.944
add totals together...
.576 + 1.152 + 1.944=3.672
