Question

find the total surface area and the latter surface area of the cube whose dimensions are land is equal to 9 cm breadth is equal to 7 cm height is equal to 3 cm

Answer 1

Answer:

TSA = 222 cm²

CSA = 96 cm²

Step-by-step explanation:

Length = 9 cm

Breadth = 7 cm

Height = 3 cm

Then, TSA = 2(lb+bh+hl) = 2((9)(7) + (7)(3) + (3)(9)) = 2(63+21+27) = 2(111)

= 222 cm²

And, LSA = 2h(l+b) = 2(3)(9+7) = 6(16) = 96 cm²
