Lets convert the fraction first to ease the calculations:
2 5/8 = 16/8 + 5/8 = 21/8
so now we can operate easily, to calculate we need to multiply 21/8 by 2/3 that is because, if 1/3 is used then 2/3 are left over (1/3 + 2/3 = 1, the total), so we have:
(2/3)(21/8) = (2*21)/(3*8)
= 42/24
= 21/12
= 7/4
so 7/4 are left over
184 cubes difference
Explanation:
First guy made a 2x2x2 (L x W x H)
L: 2 x 2 = 4 ( twice as long)
W: 2 x 3 = 6 ( three times as wide)
H: 2 x 4 = 8 ( four times as high)
New block:
4 x 6 x 8 = 192
192 - 8 = 184 cubes different
Answer: x=\pi n,\:x=\frac{\pi }{4}+\pi n
Step-by-step explanation:
-2 ≤ x < 8 is the answer.
