# HOW TO CALCULATE VOLUME OF CONCRETE IN A CANTILEVER RETAINING WALL

hello everyone. In today blog we will learn about HOW TO CALCULATE VOLUME OF CONCRETE IN A CANTILEVER RETAINING WALL. This is very important in interview point of view. so lets start.

### QUESTION: Calculate volume of concrete in a 50' long and 10' high cantilever retaining wall. other dimensions are given below.

SOLUTION:

GIVEN DATA:

Cantilever retaining wall basically consist of 2 parts ( Slab & Stem).

Width of slab = w =10’
Thickness of slab = t = 8” = 0.6’

Top Width of stem = a = 0.6’
Bottom width of stem = b = 1.67’
Height of stem = h = 10’

Length of Retaining wall = L= 50ft

Volume of the retaining wall = Volume of slab + Volume of stem

Volume of slab = W * t * L
Volume of slab = 10*0.6*50 = 333.3 cft

Volume of the stem = {(a+b)*h/2} * L

= { (0.6+1.67)*17/2} *50

= 990.2 cft

Total volume of retaining wall = 333.3 + 990.2 = 1323.5 cft
