Question

length =15cm breadth =1.2cm height =8cm . find the total surface area of a cuboid .​

Answer 1

Answer:

tsa=2(lb+bh+hl)

=2(15*1.2+1.2*8+8*15)

=2(18+9.6+120)

=2(147.6)

=295.2cm2

Answer 2

we know that the total surface area of cubiod =2(LB+BH+HL)

Length = 15 cm

Breadth = 1.2 cm

height = 8 cm

then ,total surface area of a cubiod = 2(lb+bh+hl)

=2[(15×1.2)+(1.2×8)+(8×15)]

=2[18+9.6+120]

=2×147.6

=295.2

so,the total surface area of a cubiod is 295.2
