Detailed Solution
Download Solution PDFGiven:
length, breadth, and height are 7 cm, 5 cm, and 9 cm, respectively.
Formula used:
TSA(Cuboid) = 2 x (LB + BH + HL)
L = Length
B = Breadth
H = Height
TSA = Total Surface Area
Solution:
TSA = 2 x [(7)(5) + (5)(9) + (9)(7)]
TSA = 2 x [35 + 45 + 63]
TSA = 2 x 143
TSA = 286 cm2
Hence, the correct option is 3.
