Question

Please tell questions 1 and both parts

Answer 1

here is your answer
length of the cuboid is equal to 8 m
breath of the cuboid is equal to 12 M
height of the cuboid is equal to 3.5 m
total surface area is equal to 2 (lb+bh+hl)
=2(8*12+12*3.5+3.5*8)
=2(96+42+28)
=2*166= 332m. square
lateral surface area is equal to 2h(l + b)
=2*3.5(8+12)=7*20=140m.sq
please mark it as brilliant

Answer 2

l=8m

b=12m

h=3.5m

TSA = 2(lb+bh+lh)

= 2(8*12 + 12*3.5 + 3.5*8)

= 332 sq. m

LSA = 2h(l+b)

= 2*3.5 (8+12)

= 140 sq. m
