Find the LSA,TSA and Volume of the cuboids with the following measures. a) Length = 7m, breadth = 3m and height = 2m b) Length = 5.6m, breadth = 3m and height = 1.2m
Answers
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
