Cuboid formulas
$$ V = l \cdot w \cdot h $$
$$ P = 2 l w + 2 l h + 2 w h $$
surface area
$$ d^2 = l^2 + w^2 + h^2 $$
$$ A_L = 2 l h + 2 w h $$
lateral area
example 1:ex 1:
Find the volume of a cuboid with dimensions of 10 cm length, 4 cm width, and 7 cm height.
example 2:ex 2:
The volume of a cuboid is 5000 cm3. Find the height of a cuboid if the length is 50 cm, and the width is 20 cm.
example 3:ex 3:
Find surface area of a cuboid if length is 3 cm, width is 4 cm and body diagonal is 15 cm.
