Answers:
= 181440
t2 = 36 years
8a3 = 1728
a3 = 216
a = 6
Surface area of larger cube
surface area of each smaller cube = 6.(6)2
= 216
Required ratio = 864 : 216 = 4 : 1
P = 400×2.5
P = Rs. 1000
x2+2x = 56643
x2+2x–56643=0
x2+239x–237x–56643=0
x(x+239)–237(x+239) = 0
x = 237 and – 239
Larger number = 237+2 = 239
