Answer 2

TSA = 94 , CSA = 70, HEIGHT = 5m

Since CSA = 2h(l+b)

it implies 2h(l+b) = 70

h(l+b) = 35

5(l+b) = 35 (h = 5)

l+b = 7 eq 1.......

TSA = 94

TSA = 2 (lb + bh + hl )

lb + bh + hl = 47

lb + 5b + 5l = 47

lb + 5 (b+ l) = 47

lb + 5×7 = 47 ( by eq 1)

lb = 47 - 35

lb = 12 eq2......

Area of base = l×b

= 12 m² ( by eq 2 )

Volume of cuboid = l×b×h

= 12× 5

= 60 m³
