# Rectangular Solid Calculator

Given below is the online rectangular solid calculator which helps you to calculate the Lateral Area, Surface Area and Volume of a three-dimensional rectangular box (cuboid) using its length, height and width. The lateral area of a rectangular block is the area of all the lateral faces (side faces alone). The surface area of a rectangular solid is the sum of the areas of all six sides. The lateral area, Surface area and Volume of a cuboid is given as LA=h(2L+2W), SA=2(lw+lh+wh) and V=lwh.

### Example:

Find the volume, lateral and surface area of a rectangular solid (cuboid) whose length, width and height are 30cm, 10cm and 20 cm.

#### Lateral Area Calculation:

LA = h(2l + 2w)

= 20[(2 x 30) + (2 x 10)]

= 1600 cm^{2}

#### Surface Area Calculation:

SA = 2(lw + lh +wh)

= 2[(30x10) + (30x20) + (10x20)]

= 2200 cm^{2}

#### Volume Calculation:

V = w x h x l

= 10 x 20 x 30

= 6000 cm^{3}
