Question

Three cubes each of side 7 cm are placed together end to end. The volume of the resulting cuboid will be

Answer 1

Answer:

1029

Step-by-step explanation:

Edge of all the cubes = 7cm

To find volume of a cube the formula is

a×a×a

Volume of one cube = 7×7×7 =343

Volume of three cubes = 343+343+343 = 1029

So, volume of resulting cuboid is 1029 cm

Answer 2

Answer:

1029 cm cube

Step-by-step explanation:

when they are placed together end to end

length= 7+7+7= 21cm

breadth and height = 7cm

you can understand this from the photo that I have attached

Volume of cuboid= l*b*h

= 21*7*7 cm cube

= 1029 cm cube
