Question

to use flat cut out to form cube cuboid parameters obtained for volume and total surface area​

Answer 1

Answer:

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

i) cube:

Measure the edge of the cube.

Let edge a units 1) Total surface area=(TSA)=6a^2 square

=

units

2) volume =(V)=a^3 cubic units

ii) find dimensions of the cubiod Let length=1 units

breadth= b units

Height= h units 1) TSA=2(lb+bh+h)sq units

2) volume=lbh cubic units

iii)measure the slant height =l units

Height =h units

Base perimeter = p units Of the pyramid

1)TSA=pl/2 +2xarea of the polygon 2) volume=1/3x(base area)xaltitude

iv) cone

Find the dimensions of the cone

Radius = r units

Slant height=units

Height =h units 1)TSA=curved surface area+base area

=pixrl+ pixr^2

=pixr(1+r) sq units

Where = sqrt(h^2+r^2)

2) volume=1/3x(base area)x(altitude) =1/3xpixs^2xh cubic units
