Complete question :
How many cubic blocks of side length of 17 inch would it take to fill a rectangular prism with a length width and height of 3/7 inch 1/7 inch and 3/7 inch
Answer:
9 cubic blocks
Step-by-step explanation:
The volume of a rectangular prism is given as :
V = Length * width * height
V = 3/7 * 1/7 * 3/7 = 9 / 343 in³
The volume of block clube:
Take the cube of the side length :
(1/7)^3 = 1 / 343 in³
Number of cubic blocks required :
Volume of prism / volume of cube
9 / 343 ÷ 1 / 343
9 / 343 * 343 /1 = 9
Hence, 9 cubic cubes are needed to fill the rectangular prism

Answer:
6√3
Step-by-step explanation:
Let's take the vertical side in the middle as y and the side on the left as z.
We have:
from the right triangle on the right:
9²+y²=x²
from the right triangle over the big triangle:
z²+x²=(9+3)²=12²
from the right triangle on the left:
3²+y²=z²
We can use substitution in our three equations to get x.
9²+y²=x²
z²+x²=12²
3²+y²=z²
First, solve for y² in terms of x². We want everything in terms of x so we can solve for it.
9²+y²=x²
subtract 9² from both sides
x²-81 = y²
plug that into the third equation
3²+(x²-81)=z²
x²-72=z²
z²+x²=144 (the second equation)
plug x²-72 for z²
x²-72+x² = 144
add 72 to both sides
2x² =216
divide both sides by 2 to isolate x²
x²=108
square root both sides to get x
x = √108 = 6√3
