Answer 1

Answer:

Step-by-step explanation:

questions based on cuboid total surface area

Total Surface Area of cuboid = 2 * (length * width + Length * height + width * height)

Q1 . A cuboid has dimensions   2 , 3 & 4 cm

Total Surface Area of cuboid = 2 *  ( 2 * 3  + 2*4 + 3 *4)

= 2( 6 + 8 + 12)

= 2 * 26

= 52 cm²

Q1 . A cuboid has dimensions   5 , 3 & 4 cm

Total Surface Area of cuboid = 2 *  ( 5 * 3  + 5*4 + 3 *4)

= 2( 15 + 20 + 12)

= 2 * 47

= 94 cm²

Q1 . A cuboid has dimensions   2 , 2 & 3 cm

Total Surface Area of cuboid = 2 *  ( 2 * 2  + 2*3 + 2 *3)

= 2( 4 + 6 + 6)

= 2 * 16

= 32 cm²
