The surface area of a $$12 cm \times 6 cm \times 4 cm$$​ brick is:

Correct option is C

Given:

Dimension of the brick =$$12 cm \times 6 cm \times 4 cm$$​​

Formula Used:

Surface area of cuboid =$$2(lb+bh+lh)$$​​

Solution:

The surface area of brick = 2 ((12)(6) + (6)(4) + (12)(4))

= 2 (72+24+48)

= 2(144)

= 288$$cm^2$$​​
