Answer: height=13.63 cm volume=10222.5 cm³

Step-by-step explanation:

TSA=2×LSA

2(lb+bh+lh)=2×{2h(l+b)}

lb+bh+lh=2h(l+b)

let l=30cm b=25cm

750+25h+30h = 2h(30+25)

750 + 55h = 110h

750 = 55h

h=750÷55

h= 13.63cm

volume=lbh

           =30×25×13.63

           =750×13.63

           =10222.5 cm³
