Question

if squre of edge and half of whole surface area is equal find the ratio of height length and breadth of rectangular parallelepiped​

Answer 1

Let the angle be 5x,4x nd 2x.

TSA=2(lb +bh +hl)=1216

2(20x²+8x²+10x²)=1216

76x²=1216

x²=1216/76

x²=16

x=4cm.

Dimensions are 20cm,16cm nd 8cm.

Volume=lbh

=>20*16*8

=2560cm².
