Answer:
First one. 136
Second one. 9
Third one. 200
Fourth one. 360
Step-by-step explanation:
First one
2x2x2 is 8
The volume of the small square is 8
now we have to do 8x4x4
That is 128
128 + 8 is 136
Second one
first lets do 1x1x5
This is 5
then lets do 4x1x1
this is 4
5 + 4 is 9
Third one
lets do 2x4x3
this is 24
now lets do 11x4x4
this is 176
176 + 24 is 200
Fourth one
Lets do 4x4x5
This is 80
now lets do 4x14x5
this is 280
280+80 is 360
136 cubic feet
2x2x2= 8
4x4x8 = 128
128 + 8 = 136
Answer: look at the attached image
<u>As per diagram we have:</u>
<u>As per 30° right triangle property:</u>
<u>Area of triangle:</u>
x=3k
y=3k
z=4k
x+y+z=180
3k+3k+4k=180
10k=180
k=180/10
k= 18
z=4*18
z=72
answer: 72
