Question

Answer this question with steps please

Answer 1

Total surface area of a cuboid = 2{lb+bh+hl}

Here Length = 60cm

Breadth = 35cm

Height = 30cm

TSA = 2{(60×35)+(35×30)+(30×60)}

= 2{2100+1050+1800}

= 2 × 4950

= 9900 cm²

Hope it helps....

Answer 2

Dimensions of cuboid

Length(l) =60cm

Width(w) = 35cm

Height(h) = 30cm

Surface Area of cuboid, SA

$SA = 2lw + 2lh + 2hw \\ = 2 \times 60 \times 35 + 2 \times 60 \times 30 + 2 \times 30 \times 35 \\ = 4200 + 3600 + 2100 \\ = 9900$

Surface Area is 9900cm^2
