Calculate the surface area of an open cuboid which is 12 cm long, 8cm wide, 6cm high

432 cm²

Step-by-step explanation:

To find the surface area of a cuboid, there is a formula.

2lw+2lh+2hw

Length is l, height is h, and width is w.

2 (12) (8) + 2 (12) (6) + 2 (6) (8)

Multiply all the terms.

336+96

Add both the terms.

= 432

The surface area of the open cuboid is 432cm².

432 cm²

Step-by-step explanation:

The formula.

2lw+2lh+2hw

Length is l, height is h, and width is w.

2 (12) (8) + 2 (12) (6) + 2 (6) (8)

336+96

= 432

The surface area of the open cuboid is 432cm²
