Question

The length breadth height of cuboid is 70cm:8cm:1.2m.find out the volume ,total surface area, lateral surface area of cuboids.​

Answer 1

T.S.A (TOTAL SURFACE AREA) - 2(L*B+B*H+H*L)

2*9920

19840CM2

L.S.A - 2h(L+B)

2*120(70+8)

240*78

18720CM2 that is lateral surface area

volume of the cuboid- L*B*H

70*8*120

67200CM3

The length breadth height of cuboid is 70cm,8cm and 1.2m.Find out the volume ,total surface area, lateral surface area of cuboid.

❥${\underline{\underline{\huge{\mathtt{Solution:-}}}}}$

Given :-

• Length of cuboid = 70 cm.
• Breadth of cuboid = 8 cm.
• Height of cuboid =1.2 m = 120 cm.

To find:-

• Volume of cuboid.
• Total surface area of cuboid.
• Lateral surface area of cuboid

Formula Used:-

•Volume of cuboid = Length×Breadth× Height

• Total surface area of cuboid=2(L×B+B×H+L×H)

• Lateral surface area of cuboid=2h(L+B)

Calculations:-

Volume of cuboid= (70×8×120)cm³

= 67200 cm³

Total surface area of cuboid=

2(70×8+8×120+70×120) cm²

=19840 cm²

Lateral surface area of cuboid=2×120(70+8) cm²

=18720 cm²

❥${\underline{\underline{\huge{\mathtt{Answer:-}}}}}$

• Volume of cuboid is 67200 cm³.
• Total surface area of cuboid is 19840 cm².
• Lateral surface area of cuboid is 18720 cm².
