Question

Q.24)Draw a rough sketch of a polygon with 7 sides and name it as ABCDEFG
a) Mark two point P and Q in the interior of it.
b) Mark two point R and S in exterior of it.
c) Draw two diagonals and name them
please give the answer​

Answer 1

length =12cm, breadth = 8 cm and height = 4.5 cm

∴ Volume of cuboid = l x b x h

= (12 x 8 x 4.5) cm3= 432 cm3

∴ Lateral surface area of a cuboid = 2(l + b) x h

= [2(12 + 8) x 4.5] cm2

= (2 x 20 x 4.5) cm2 = 180 cm2

∴ Total surface area cuboid = 2(lb +b h+ l h)

= 2(12 x 8 + 8 x 4.5 + 12 x 4.5) cm2

= 2(96 +36 +54) cm2

= (2 x186) cm2

= 372 cm2
