Question

What is the capacity of a box in ST units it
0.08m long, 1 cm wide and 400 mm deep?
(A) 3.2 x 10-3 m-3
(B) 3.2 x 10-5 m-3
(C) 3.2 x 10-4 m -3
D) 3.2 x 10-6 m-3
​

Answer 1

Answer:(c)3.2*10^-4

Explanation:

Capacity means volume here

Volume=length*wide*deep

Volume=0.08m * 1cm* 400mm

Since 1cm=10^-2m

and 1mm=10^-3m

Volume=((8*10^-2)m* 10^-2m *(400*10^-3)m)

Volume=(8*1*400)*(10^-2*10^-2*10^-3)*m^3

Volume=(3200)*(10^-7)*m^3

Volume=3.2*10^-4 m^3

THIS IS SO SIMPLEST EXPLANATION ..I MADE IN MY LIFE
