Question

27 What is the length of wood in a
containing, 20 dralls of the length of wood in
leach ball is 200cm
packet​

Answer 1

Answer:

Step-by-step explanation:

Volume of the log of wood=200×20×10=40000 cm³

Volume of each block=10×5×4=200 cm³

Number of blocks= Volume of log of wood÷volume of each block

                           = 40000÷200=200

Hence number of blocks will be 200.

TSA of all blocks= number of blocks×TSA of each block.

TSA of each block=2(lb+bh+lh)=2[(10)(5)+(5)(4)+(4)(10)]=2[110]=220 cm²

TSA of all blocks=200×220=44000 cm²
