Question

Find the surface area of a cuboid whose lenght 20cm breadth 15cm and height 4 cm​

Answer 1

TSA of cuboid =2(lb+bh+hl)

height(h)of cuboid=4cm

length(l)of cuboid=20cm

breadth(b)of cuboid=15cm

so,TSA of cuboid= 2(20×15+15×4+4×20)

=2(300+60+80)

=2(440)

=880cm²

hence,the surface area of cuboid is 880cm².
