The maximum error in calculating the surface area of the rectangular box is 184.
What is a Rectangle?
A rectangle is just a quadrilateral with equal angles and opposite sides that are equal & parallel. There are several rectangle items all around us. Each rectangle form is distinguished by two dimensions: length and width.
The length of a rectangle is the longer side, while the width is the shorter side.
Now according to the question;
The total surface area of the rectangle is;
L= length, W = Width and H = height
A = 2LW + 2WH + 2LH
Differentiating the area;
dA=[2*(dL)*W+2*L*(dW)]+[2*(dW)*H+2*W*(dH)]+[2*(dL)*H+2*L*(dH)]
dA is the maximum error.
As, the error obtained on each side is same as 0.2.
dL=dW=dH=0.2cm
L=100cm
W=70cm
H=60cm
Simply enter the value into the above calculation, and the resulting value is your maximum error.
dA=[2*(0.2)*100+2*70*(0.2)]+[2*(0.2)*70+2*60*(0.2)]+[2*(0.2)*60+2*100*(0.2)]
dA=184
Therefore, the maximum error in calculating the surface area of the box is 184.
