Question

a cube with an edge 7 cm and a cuboid measuring 7cm * 4cm* 8cm are kept on the table which shape har more volume?​

Answer 1

Answer:

Volume of cube = 343 cu cm

Volume of cuboid = 224 cu cm

Answer 2

Answer:

Cube has more volume.

Given:

Two shapes are kept on table.

First one is a cube whose edge is 7 cm.

Other one is a cubord measuring 7 cm × 4 cm × 8 cm.

For cubord:

Let us suppose;

Length = 7 cm

Breadth = 4 cm

Height = 8 cm

To find:

Which shapes has more volume?

For finding the volume of cube and cubord we should have to what formula should be used here.

For cube:

Volume of cube = a³ cubic unit

Where, a = Edge

For cubord:

Volume of cuboid = lbh cubic unit

Where, l = Length, b = Breadth and h = Height

Now:

Volume of cube = 7³ cm³

Volume of cube = 343 cm³

And:

Volume of cubord = (7 × 4 × 8) cm³

Volume of cubord = 224 cm³

Here we get that:

Volume of cube = 343 cm³

Volume of cubord = 224 cm³

∴ Cube has more volume.
