Units of square inches are never equal to units of cubic inches, so we presume the statement of the problem applies to the numerical values in in² and in³.
The volume of a cuboid of length L, width W, and height H is
... V = LWH
The area is
... A = 2(LW + H(L+W))
You want these to be equal for L=9, W=4, and H=x.
Equating the expressions, we have
... 9·4·x = 2(9·4 +x(9+4))
... 36x = 2(36 +13x) . . . . . simplify a bit
... 36x = 72 + 26x . . . . . . simplify more
... 10x = 72 . . . . . . . . . . . . subtract 26x
... x = 7.2
The dimension represented by x is 7.2 inches.
Answer:
759 rolls
Step-by-step explanation:
Total rolls = 1265
Number of batches = 5
Since each batch hs the same number of rolls:
Number of rolls per batch :
1265 / 5
= 253 rolls per batch
Number of rolls in 3 batches :
253 * 3 batches
= 759 rolls
Answer:
angle1ans=105 angle 2 and=75
Step-by-step explanation:
angle with 75 is equal to angle 2 and angle 1 is calculated by taking
180-75=105
This is an altitude. Shown by the right angle on the side opposite the point.
