Answer:

18 ft³

Step-by-step explanation:

Consider the given figure showing the steps to consists of 3 rectangle prism or cuboid.

The cubic feet of concrete necessary = sum of the volume of the 3 cuboid/rectangular prism

Volume = l*w*h

Dimension of each cuboid:

Note that 1 ft = 12 inches

First cuboid:

Length (l) = 48 in = 48/12 = 4 ft

Width (w) = 36 in = 36/12 = 3 ft

Height (h) = 9 in = 9/12 = 0.75 ft

Volume = 4*3*0.75 = 9 ft³

Second cuboid:

Length (l) = 48 in = 48/12 = 4 ft

Width (w) = 24 in = 24/12 = 2 ft

Height (h) = 9 in = 9/12 = 0.75 ft

Volume = 4*2*0.75 = 6 ft³

Third cuboid:

Length (l) = 48 in = 48/12 = 4 ft

Width (w) = 12 in = 12/12 = 1 ft

Height (h) = 9 in = 9/12 = 0.75 ft

Volume = 4*1*0.75 = 3 ft³

Cubic feet of concrete necessary for the steps = 9 + 6 + 3 = 18 ft³

Answer:

Check it below

Step-by-step explanation:

1) The Boxplot is a visual tool to easily find the quartiles of a Distribution. To construct a boxplot it's necessary to organize the data, find at least the upper (3rd Quartile) and lower quartile (1st Quartile), and register the maximum and the minimum value.

2) This graph confirms that the South American ones have much more water than the North American counterparts. Notice the Upper Quartile, (the top of the box) for the Southern ones, it's over 100,000 yrds³. And Compare to the Northern one.
