in a house a hall is 20 m long , 15 m wide and 5 m high . its interior has to be covered with mat . what will be the total expenditure if it costs rs . 10 per square m ?
n0 = 20.0
n1 = 15.0
n2 = 5.0
n3 = 10.0
t0 = n0 * n1
t1 = n0 * n2
t2 = n1 * n2
t3 = t0 * 2.0
t4 = t1 * 2.0
t5 = t2 * 2.0
t6 = n3 * t3
t7 = n3 * t4
t8 = n3 * t5
t9 = t6 + t7
answer = t9 + t8
