Step 1; multiple equation 2 by -2: 14x+8y=-18
step2: subtract this new equation from equation 1 to eliminate x:
2y-8y=18-(-18)
-6y=36
y=-6
step 3: substitute y=6 in equation 2: -7x-4*(-6)=9, -7x=-15, x=15/7
Create a prison using the blocks. For example, a length of 4 blocks, a width of 2 blocks, and a height of 1 block. This creates a prism that contains 8 blocks.
Now, find multiply 1/4 by each measurement to find the size of each measure.
1/4 x 4 = 1 = length
1/4 x 2 = 1/2 = width
1/4 x 1 = 1/4 = height.
Now you have the three measurements, multiply for the volume!
V = l x w x h
V = 1 x 1/2 x 1/4 = 1/8.
Therefore, the rectangular prism has a volume of 1/8 cubic meters!
