Question

The surface area of cube is 1734 cm square .find the lateral surface area

Answer 1

Answer:

=TSA of cube =1734cm²

=6×Side²=1734

=side²=1734/6

=side=√289

=side=17cm

LSA of cube = 4×side²

=4× 17²

=4×289

=1156cm²

Answer 2

Given:

• The surface area of cube is 1734 cm²

To find out:

Find the lateral surface area.

Formula used:

• Total surface area of cube = 6 l²

• Lateral surface area of cube = 4l²

Solution:

Total surface area of cube =1734cm²

➭6l²=1734

➭l²=1734/6

➭l=√289

➭l=17cm

Now,

Lateral surface area of cube = 4l²

=4× 17²

=4×289

=1156cm²

Extra:

• Surface area of cuboid = 2 (lb + bh + hl)

• Surface area of a cube = 6 l²

• Lateral surface area of cuboid = 2h ( l + b )

• Volume of cuboid = l × b × h

• Volume of cube = l³
