Question

A cuboid has total surface
area of 40m2 and it's lateral surface area ( Pie h 5A)
is 26m2? Find the area
of its base?​

Answer 1

Answer:

Total surface area = 2( Surface area of base ) + (Surface area of 4 walls)

40=2(S)+26

2S=14

S=7 m2

Hence, surface area of base is 7 m2.

Answer 2

Answer:

7$m^{2}$

Step-by-step explanation:

T.S.A = 40 $m^{2}$

L.S.A = 26 $m^{2}$

area of base = 1/2 ( T.S.A - L.S.A ) = 1/2 x 14 = 7 $m^{2}$
