Two cubes each of side 10 cm are joined end to end forming a rectangular shape solid find the surface of the resulting rectangular shaped. solid
Answers
Answer:
1000 cm²
Steps:
Cube of side 10 cm. So,
Length = 10 + 10 cm (adding the side 10 twice)
Breadth = 10 cm
Height = 10 cm
Adding the cubes make a cuboid.
Surface area of a cuboid = 2( lb + bh + hl )
2( 10 x 20 + 10 x 10 + 10 x 20 )
2( 200 + 100 + 200 )
2 (500)
= 1000 cm²

Answer:
1000 square centimeters.
Step-by-step explanation:
Given that the cubes are solids then it means they are closed cubes.
When we join them to form a cuboid the length changes but the width, and the height remains constant.
That is our new dimensions will be :
Length = 10 + 10 = 20 cm
Width = 10 cm
Height = 10 cm
The surface area means we need to get the total area of all the faces.
The area of each face = length × Width
The area will thus be:
2 × 20 × 10 + 2× 10 × 10 + 2 × 10 × 20 = 1000
The surface area of the cuboid formed is given as :
1000 square centimeters.
