Answer:
B 2 2/3
Step-by-step explanation:
Triangles ADB and CDB are similar. Therefore similar parts can form a proportion.
AD/DB = DB/DC
AD = ?
DB = 4
DC = 6
x/4 = 4/6 Cross multiply
6x = 16
6x/6 = 16/6
x = 2 4/6 or x = 2 2/3
It's B
The formula for volume is Length x width x height.
Bottom: 18 * 12 * 8 = 1728 cubic centimeters.
Middle: 12 * 8 * 6 = 576 cubic centimeters.
Top = 4 *4*4 = 64 cubic centimeters.
Total: 1728 + 576 + 64 = 2368 cubic centimeters.
First set it up in an equation equal to 33
33= 7 + x + x
33 = 7 = 2x
26 = 2x
13 = x
plug x value back into equation
