Each box weighs 4 pounds
Step-by-step explanation:
Total weight of bag after packing = 36 pounds
Weight of empty bag = 4 pounds
If we exclude the weight of empty bag from the total weight we will get the weight of the boxes.
So,
Weight of boxes = 36-4 =32 pounds
So the weight of identical boxes is 32 pounds.
Total boxes = 8
So,
Each box weighs 4 pounds

Step-by-step explanation:
Given : 178 meters in 2 seconds.
To find : How many meters in 10 seconds ?
Solution :
Applying unitary method,
In 2 seconds there is 178 meter.
In 1 second there is meter.
In 1 second there is 89 meter.

Answer:
x=2
Step-by-step explanation:
8x-10-4x=-1/2(12x-20)
4x-10=-6x+10
4x+6x=10+10
10x=20
x=2
The answer is:
The reason is:
bottom one is a square prism. the volume formula is l x w x h. 9 x 9 x 9
square prism : 729
then the top one is a triangular prism. which is 1/2b x a x a
so 3.5 x 9 x 9
triangular prism: 283.5
then add these 2 numbers
1012.5
