Sketch the solid whose volume is given by the integrated integral
\(\int\limits_0^1 {\int\limits_0^1 {\left( {4 - x - 2y} \right)} } dxdy\)

Given:- Double integrated integral

\(\int\limits_0^1 {\int\limits_0^1 {\left( {4 - x - 2y} \right)} } dxdy\)

To draw:- Solid volume is given by integrated integral

Step by Step Solution

TABLE OF CONTENTS

Step (1):- Defining volume

The volume before the surface z=g(x,y) and below the region D is \(\int {\int\limits_D {\left( {4 - x - 2y} \right)dxdy} } \)represents the volume below the plane z=4-x-2y and a square \(x \ge 0,y \le 1\)

Step (2):- Calculating volume by solving integral

\(\begin{array}{l}\int\limits_0^1 {\left( {\int\limits_0^1 {4 - x - 2y} } \right)dxdy} \\\int\limits_0^1 {\left( {4x - \frac{{{x^2}}}{2} - 2yx} \right)} _0^1dy\\\int\limits_0^1 {\left( {4\left( 1 \right) - \frac{{{{\left( 1 \right)}^2}}}{2} - 2\left( 0 \right)\left( 1 \right) - 0} \right)} _0^1dy\\\int\limits_0^1 {\left( {\frac{7}{2} - 2y} \right)} dy\end{array}\)

Step (3):- Integrating w.r.t y

\(\begin{array}{l}\int\limits_0^1 {\left( {\frac{7}{2} - 2y} \right)} dy = \left( {\frac{7}{2}y - 2.\frac{{{y^2}}}{2}} \right)_0^1\\\frac{7}{2} - 2.\frac{{{1^2}}}{2} - 0\\\frac{7}{2} - 1 = \frac{5}{2}\end{array}\)

Therefore, the volume of the solid is \(\frac{5}{2}\)cubic units.
