Question

28.The lateral surface area of a cube whose side measures 6 cm is-​

Answer 1

Answer:

A cube is a 3-D solid with 6 congruent square faces, four of those are lateral faces. The 12 edges are of congruent length.

Length of each edge, a = 6 cm (by data)

Area of each face of a cube = a² = 6² cm²

LSA of a cube = 4a² = 4×6² cm² = 144 cm²

TSA of a cube = 6a² = 6×6² cm² = 216 cm²

Answer 2

Answer:

144

Step-by-step explanation:

Formula

Lateral Surface Area of cube = 4a^2 [where a=side]

$4{a}^{2} \\ 4 \times {6}^{2} \\ 4 \times 36 \\ 144 {cm}^{2}$
