Answer:
24 + 12 = 36
Step-by-step explanation:
find the volume of the upper left part by finding the dimensions
it already gives 2 side lengths: 2 and 2. To find the 3rd side length you can take 5 - 2 to get 3. 3*2*2 = 12
find the volume of the bottom portion by finding the dimensions. we are given 2 sides again: 2 and 2. to get the upper long side, we can do 4 + 2 to get 6. 6*2*2 = 24
24+12= 36cm^3
Not exactly sure which equation you meant:
3(100-b)=6b
300-3b=6b
300=9b
b= about 33
100-3b=6b
100=9b
b=about 11
Answer: 300 cubic inches
Explanation:
Imagine slicing the T shape into two pieces such that we have two rectangular blocks.
- The larger block down below has volume of 3*12*5 = 180 cubic inches.
- The smaller block on top has volume of 8*3*5 = 120 cubic inches
The overall volume of this T shape is 180+120 = 300 cubic inches.
Answer:
C.
