Question

Find the volume, surface area and total surface area


length=22cm, breadth=12and. height=7.5​

Answer 1

Question:Find the volume, surface area and total surface area of cuboid of length=22cm, breadth=12and. height=7.5

Answer:

Given Length=22cm, breadth=12cm and height=7.5cm

We know that volume of cuboid= length×breadth × height

V = (22 × 12 × 7.5) V = 1980cm3

We know that, total surface area of cuboid= 2(l b + b h + h l)

Surface area = 2 (22 × 12 + 12 × 7.5 + 7.5 × 22) Surface area = 2 (264 + 165 + 90)

Total Surface area = 1038cm2

We know that lateral area of cuboid= 2 [(l + b) × h]

Lateral surface area = 2 [(22 + 12) × 7.5]

Lateral surface area = 510 cm2

Answer 2

Correct Question :-

Find the volume, surface area and lateral surface area :-

• Length = 22 cm
• Breadth = 12 cm
• Height = 7.5 cm

Answer ::

• The volume of cuboid is 2475cm³
• The surface area of cuboid is 1215cm²
• The lateral surface area of cuboid is 555cm²

Step-by-step explanation :-

To Find :-

• The volume
• The surface area
• Lateral surface area

Solution :-

As we know that,

Volume of cuboid :- ( l × b × h ) units,

➟ ( 22 × 15 × 7.5 )

➟ 2475

The volume of cuboid is 2475cm³.

As we know that,

Surface area of cuboid :- 2 ( lb + bh + hl ) sq. units,

➟ 2 ( 22*15 + 15*7.5 + 7.5*22 )

➟ 2 ( 330 + 112.5 + 165 )

➟ 2 × 607.5

➟ 1215

The surface area of cuboid is 1215cm².

As we know that,

Lateral surface area of cuboid :- 2 [ ( l + b ) × h ] sq. units,

➟ 2 [ ( 22 + 15 ) × 7.5 ]

➟ 2 [ 37 × 7.5 ]

➟ 2 × 277.5

➟ 555

The lateral surface area of cuboid is 555cm².
