Question

the side of cube is measured as (7.5+_ 0.1 )cm.find the volume of the cube.

Answer 1

Howdy!!

your answer is ---

Given,

side of cube a = ( 7.5 +_ 0.1) cm

so, volume V = side^3
= 421.85 cm^3

now, ∆V/V = 3×∆a/a

=> ∆V/421.85 = 0.04

=> ∆V = 0.04×421.85 = 16.85cm


therefore ,


Volume of cube = (421.85 +_ 16.85)cm^3



hope it help you
