Answer 1

Answer:

L= 15m

B= 6m  

H= 9dm = 0.9m

V = LBH

   = 15 x 6 x 0.9

   = 81 dm³

LSA = 2H(L+B)

       =2(0.9)(15 + 6)

        = 1.8 X 21

         = 37.8  dm²

TSA = 2lb+2lh+2hb

       = 2(15)(6) + 2(15)(0.9) + 2(6)(0.9)

       = 180 + 27 + 10.8

       =217.8 dm²

Hope it helps!!!!!!

Find the volume, lateral surface area and total surface area of the cuboid.

$volume \: of \: cuboid \: = lbh$

$= 15 \times 6 \times 0.9$

$=81$

$lateral \: surface \: area \: = 2h(l +b )$

$= 2 \times 0.9(15 + 6)$

$= 2 \times 0.9 \times 21$

$= 37.8$

$total \: surface \: area \: of \: cuboid \: = 2( lb+bh +lh )</p><p>$

$2(15 \times 6 \: + \: 15 \times 0.9 \: + \: 6 \times 0.9)$

$2(90 + 13.5 + 5.4)$

$2 \times 108.9 = 217.8$
