Question

Total Surface Area Of Cuboid.....??​

Answer 1

Answer:

$\bf\underline\red{Solution:-}$

$\bf{Total\:surface\:area\:of\:a\:cuboid}$

$\longrightarrow \sf{2(lb + bh + hl)}$

$\longrightarrow \sf{2[(l \times b) + (b \times h) + (h \times l)]}$

$\sf{What\:is\: Cuboid?}$

• In geometry, a cuboid is a three-dimensional shape in which all sides are rectangles.

• It is a polyhedron, having 6 rectangular sides called faces, 8 vertices and 12 edges.

• These rectangular faces are at right angles to one another.

• All angles in a cuboid are right angles.

$\sf\underline\red{Additionally:-}$

$\bf{Lateral\:surface\:area\:of\:a\:cuboid}$

• $\longrightarrow \bf{2(l+b)h}$

$\bf{Volume\:of\:a\:cuboid (v)}$

• $\longrightarrow \bf{l \times b \times h }$

$\bf{Diagonal\:of\:a\:cuboid}$

• $\longrightarrow \bf{ \sqrt{l^2 + b^2 + h^2}}$

$\sf\underline\red{Properties\:of\:Cuboid:-}$

• Three dimensions of width, length and depth (or height).

• Six rectangular faces

• All vertices are 90°

• Opposite sides of the cuboid are parallel and congruent to each other.
