a rectangular gate is made using 6 straight peices of steel. the weight of the the steel is 2.5kg per metre. work out the total weight of the steel gate
Answers
In this sum ,the total length of steel pieces are not given,
so, Let Consider each piece of steel rod is= 2.5 kg ,
therefore weight of 6 pieces will be :--
6×2.5kg= 15 kg
Given : a rectangular gate is made using 6 straight pieces of steel. the weight of the the steel is 2.5kg per metre
To find : total weight of the steel gate
Solution:
Missing information :
Gate is of 5 m * 12 m
two Horizontal rod = 5 m each
two vertical rod = 12 m each
two Diagonal rod to be calculated using Pythagoras theorem
Diagonal length² = 5² + 12²
=> Diagonal length² = 13²
=> Diagonal length = 13 m
Total length of Rod = 2 ( 5 + 12 + 13)
= 2(30)
= 60 m
weight of the the steel is 2.5 kg per metre
Total Weight of Steel gate = 60 * 2.5 = 150 kg
