Answer:
Rs. 752
Step-by-step explanation:
TSA of rectangular block = 2(lb+bh+hl)
=2(100×80 + 80×60 + 60×100)
=2(8000 + 4800 + 6000)
=2×18800
=37600 sq.mm

Answer:
The estimated cost of the milling of given block is 752 RS.
Step-by-step explanation:
- In context to the given question we have to find the estimation cost of milling of a rectangular block.
- given dimension of rectangular block size 100×80×60
length = 100 mm = 10cm
breadth = 80mm = 8 cm
height = 60mm = 6 cm
- Milling area of rectangular block = 2 ( lb + bh + hl )
= 2 [ (10)(8) + (8)(6) + (6)(10) ]
= 2 [ 80 + 48 + 60 ]
=2 [ 188]
= 376 cm²
- cost of milling must be in sq.= RS 2/ cm²
Cost of Milling block = area of milling x cost per cm²
Cost of Milling block = 376 x 2
Cost of Milling block = 752 RS.
The estimated cost of the milling of given block is 752 RS.
