A figure provided in the question,

02

Step 2. Determine the weight.

Firstly, find the volume of the first brick,

v=40脳20脳20=16000鈥夆赌塩尘3[multiply]

And the volume of upper,

v=12脳10脳20=2400[simplify]

Then the volume of actual block is,

v=16000鈭�2(2400)=11200鈥夆赌塩尘3[multiplyandsubtract]

Thus, the weight of the block is,

w=112001000000(1700)=19kg[simplify]
