Question

Two cubes joined end to end to form a cuboid each cube has volume 64cm3 find the volume of cuboid

Answer 1

Two cubes are joined end to end to form a cuboid.
Each cube has volume 64 cm³
a³ = 64
a³ = 4³
a = 4

Side of the cube = 4 cm

Dimensions of cuboid :-
Length = a + a (as two cubes are joined)
= 4+4 = 8
Breadth = a = 4
Height = a = 4

Volume of cuboid = length × breadth × height
= 8 × 4 × 4
= 128 cm³

Hope it helps

Answer 2

Each cube has volume = 64 cm^3
Cuboid = 2 × cube
Volume of cuboid = 2 × Volume of cube
Volume of cuboid = 2 × 64 cm^3 = 128 cm^3

Volume of cuboid is 128 cm^3
