Answer:
Option D. 50 ft
Step-by-step explanation:
we know that
The area of the figure is equal to the area of three rectangles
so
![A=18x+(48-36)(32-11)+(18)(32)](https://tex.z-dn.net/?f=A%3D18x%2B%2848-36%29%2832-11%29%2B%2818%29%2832%29)
![A=18x+(12)(21)+(18)(32)\\A=18x+828](https://tex.z-dn.net/?f=A%3D18x%2B%2812%29%2821%29%2B%2818%29%2832%29%5C%5CA%3D18x%2B828)
Remember that the area is given
![A= 1,728\ ft^2](https://tex.z-dn.net/?f=A%3D%201%2C728%5C%20ft%5E2)
so
![18x+828=1,728](https://tex.z-dn.net/?f=18x%2B828%3D1%2C728)
solve for x
![18x=1,728-828\\18x=900\\x=50\ ft](https://tex.z-dn.net/?f=18x%3D1%2C728-828%5C%5C18x%3D900%5C%5Cx%3D50%5C%20ft)
Answer:
10692 cubic inches
Step-by-step explanation:
Since we are told to give the units in inches, let's convert the two values which are in feet.
1 ft= 12 inches
thus,
length 2.75 ft. = 33inch
breadth 4.5 ft. = 54 inch
and height is 6 inches.
Volume of a cube= length × width × height
= 33 × 54 × 6
= 10692 cubic inches
