Hey user...
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.

Hope this will help u

assume them as 5x,4x,2x.then put the formula of T.S.A.
then it willgive u the value of x ,then find the volume by lxbxh. hope so it helps you..
