Question

The total surface of a cuboid is 2350cm^2 and its Length and Breadth is 25cm and 20cm respectively find its Height

Answer 1

TOTAL SURFACE AREA =2350 CM ^2

2(LB+BH+LH) =2350

(LB+BH+LH) =2350/2

(LB+BH+LH) =1175

25×20+20×H+25×H=
1175

500+45 H= 1175

45H= 1175-500=675

H= 675/45

H=15 CM

Answer 2

2(lb+bh+lh)=2350
25*20+20h+25h=2350/2
500+45h=1175
45h=675
h=15cm
