V = L*W*H
36 cm=0.36 m
1.35 = 5 * W * 0.36 { 5* 0.36 =1.8 }
w = 1.35 / 1.8
w = 0.75 m
w = 75 cm
36 cm=0.36 m
1.35 = 5 * W * 0.36 { 5* 0.36 =1.8 }
w = 1.35 / 1.8
w = 0.75 m
w = 75 cm

given,
length=5m
height=36 cm=0.36cm
volume=1.35m3
let width of the beam be α
volume=length×bredth×height
⇒1.35=5×α×0.36
⇒α=1.35÷5×0.36
⇒α=1.35÷1.8=0.75 m
therefore,width of the log is 0.75m or 75 cm
length=5m
height=36 cm=0.36cm
volume=1.35m3
let width of the beam be α
volume=length×bredth×height
⇒1.35=5×α×0.36
⇒α=1.35÷5×0.36
⇒α=1.35÷1.8=0.75 m
therefore,width of the log is 0.75m or 75 cm
