Question

length 15 cm ,breadth 6 cm and height 9dm . Find the volume and lateral surface area , the total surface area of the cuboid

Answer 1

Given:

l=15cm

b=6cm

h=9 dm =90cm

Volume=lbh

=15×6×90

=8100cm^3

L.S.A = 2h(l+b)

=2×90(15+6)

=180×21

=3780cm^2

TSA=2(lb+bh+lh)

=2((15×6)+(6×90)+(90×15))

=3960cm^2

Answer 2

Answer:

given

length= 15m

breadth=6m

height= 9 dm= 90 CM

volume of a cuboid= l×b×h

= 15 6 90

= 8100cm^3

L.S.A of a cuboid= 2 ( l +b) ×h

= 2( 15+ 6) × 90

= 2× 21 ×90

= 3780 cm^2

T.S.A = 2( lb+bhi+hl)

= 2(15×6) +(6×90)+(90×15)

= 2(90+540+1350)

= 2×1980

= 3960 cm^2

answer is = 8100 cm^3, 3780 cm^2, 3960 cm^2
