Question

To use flat cutouts to form cube, cuboid and pyramid to obtain formula for volume and total surface area.
please help!!!

Answer 1

Step-by-step explanation:

First we have to know dimensions of the each 3-D figure.

First we have to know dimensions of the each 3-D figure.i) cube:

First we have to know dimensions of the each 3-D figure.i) cube:Let edge = a units

First we have to know dimensions of the each 3-D figure.i) cube:Let edge = a units1) Total surface area=(TSA)=6a^2 square units

First we have to know dimensions of the each 3-D figure.i) cube:Let edge = a units1) Total surface area=(TSA)=6a^2 square units2) volume =(V)=a^3 cubic units

First we have to know dimensions of the each 3-D figure.i) cube:Let edge = a units1) Total surface area=(TSA)=6a^2 square units2) volume =(V)=a^3 cubic unitsii) find dimensions of the cubiod

First we have to know dimensions of the each 3-D figure.i) cube:Let edge = a units1) Total surface area=(TSA)=6a^2 square units2) volume =(V)=a^3 cubic unitsii) find dimensions of the cubiodLet length= l units

First we have to know dimensions of the each 3-D figure.i) cube:Let edge = a units1) Total surface area=(TSA)=6a^2 square units2) volume =(V)=a^3 cubic unitsii) find dimensions of the cubiodLet length= l unitsbreadth= b units

First we have to know dimensions of the each 3-D figure.i) cube:Let edge = a units1) Total surface area=(TSA)=6a^2 square units2) volume =(V)=a^3 cubic unitsii) find dimensions of the cubiodLet length= l unitsbreadth= b unitsHeight= h units

3) volume=lbh cubic units

) volume=lbh cubic unitsiii)measure the slant height =l units

) volume=lbh cubic unitsiii)measure the slant height =l unitsHeight =h units

) volume=lbh cubic unitsiii)measure the slant height =l unitsHeight =h unitsBase perimeter = p units

) volume=lbh cubic unitsiii)measure the slant height =l unitsHeight =h unitsBase perimeter = p unitsOf the pyramid

) volume=lbh cubic unitsiii)measure the slant height =l unitsHeight =h unitsBase perimeter = p unitsOf the pyramid2) volume=1/3×(base area)×altitude

and then similarly for pyramid.

Hope my hardwork pays off to you
