Question

A metalic Sheet of a rectangular Shape with measurment 40cm by 30 cm from each corner of a Square of size 4cm is cut off and an open Box is Mad up of the remaning Sheet. Find TSA(toal surface area)​

Answer 1

Answer:

The box will have the dimensions, length =48−2(8)=32 cm

Breadth =36−2(8)=20 cm

Height =8 cm

Since the box is of the shape of a cuboid, Volume of a cuboid of length l, breadth b and height h=l×b×h

So, the volume of the box =32×20×8=5120 cm
