We will proceed as follows:
*The volume of a rectangular solid is given by the expression:
[tex]V=l\cdot h\cdot w[/tex]Therefore, it's volume will be:
[tex]V=(16)(20)(15)\Rightarrow V=4800[/tex]So, it's volume equals 4800 cm^3.
*The surface area of a rectangular solid is given by the expression:
[tex]A=2(wl+hl+hw)[/tex]So, its surface area will be:
[tex]A=2((15)(16)+(20)(16)+(20)(15))\Rightarrow A=1720[/tex]Therefore, its surface area equals 1720 cm^2.
