Answer:
A. 3 cm
Step-by-step explanation:
The smallest face has the sides 4 cm and 8 cm. If the water is 4 cm from its top, then the height of the water is
cm and the volume of the water is

The largest face has the sides 8 cm and 16 cm. If the container is placed on its largest face, then the volume of the water is

where h is the height of the water.
Equate volumes of the water:

Therefore, the water is 3 cm from the bottom.
Answer:
50
Step-by-step explanation:
if you take 138 witch equals the whole angle and subtract the second part of the abngle 88 we get 50 equaling the unknown angle
The answer would be -13=13. Its just telling you to write an equation by usiing the absolute value
If this is a cube and each side is 6ft, each face will have an area of 6ft * 6ft, or 36ft. There are 6 faces on a cube, so 36ft * 6 = 216ft² as the surface area (it's also the same as 6³, fancy huh?)
Use a protracter :) hope this helps!
