Answer:
Step-by-step explanation:
Volume of cube = (length)(width)((height)
= √5 ⋅ √5 ⋅ √5
= 5√5 in³
:::::
Volume of enlarged cube = √10 ⋅ √10 ⋅ √10 = 10√10 in³
See the pattern?
If side length is √x:
Volume = √x ⋅ √x ⋅ √x
= x√x in³
Answer:31/40
To add you have to have a common denominator. To get that you can multiply each fraction by one in different ways. 2/5 *8/8= 16/40 and 3/8* 5/5= 15/40 and then add those two to give you 31/40.
40+2=42 or 20+22=42
