Chapter 1, Problem 111SAE

Interpretation Introduction

Interpretation:

The correct reported volume of the cardboard needs to be determined.

Concept introduction:

The volume of the rectangle can be calculated as follows:

$V=l\times b\times h$

Here, l is length, b is breadth and h is height of the rectangle.

Rules for rounding off numbers are as follows:

If the number to be rounded off is followed by digit 5 or greater than 5, the number will be rounded up.

For example: Rounding off number 38, the number is followed by digit 8 which is greater than 5 thus; the number will be rounded up to the nearest ten that is 40.

If the number to be rounded off is followed by digit zero or less than 5, the number will be rounded down.

For example: Rounding off number 33, the number is followed by digit 3 which is less than 5 thus; the number will be rounded down to the nearest ten that is 30.
