Answer» (a) LSA = 40 m², TSA = 82 m², VOLUME = 42 m³ (b) LSA = 20.64 m², TSA = 54.24 m², Volume = 20.16 m³ Step-by-step explanation: QUESTION a) Length = 7m, breadth = 3m and HEIGHT = 2m Find Lateral Surface Area: LSA = Perimeter x Height LSA = 2(7 + 3) x 2 = 40 m² Find the TOTAL Surface Area: TSA = LSA + 2(Length x Breadth) TSA = 40 + 2( 7 x 3) = 82 m² Find the volume: Volume = Length x Breadth x Height Volume = 7 x 3 x 2 = 42 m³ ------------------------------------------------------------------------------ Question b) Length = 5.6m, breadth = 3m and height = 1.2m Find Lateral Surface Area: LSA = Perimeter x Height LSA = 2(5.6 + 3) x 1.2 = 20.64 m² Find the Total Surface Area: TSA = LSA + 2(Length x Breadth) TSA = 20.64 + 2( 5.6 x 3) = 54.24 m² Find the volume: Volume = Length x Breadth x Height Volume = 5.6 x 3 x 1.2 = 20.16 m³ Answer: (a) LSA = 40 m², TSA = 82 m², Volume = 42 m³ Answer: (b) LSA = 20.64 m², TSA = 54.24 m², Volume = 20.16 m³ |
