Find the surface area volume step by step plz
Answers
First Figure:
Length (l) = 6 cm
Breadth (b) = 4 cm
Height (h) = 2 cm
Total Surface Area = 2 (lb + bh + hl)
= 2 (6x4 + 4x2 + 2x6)
= 2 (32 + 8 + 12)
= 2 x 52
= 104 cm²
Lateral Surface Area = 2h (l+b) = 2 x 2 x (6+4) = 4 x 10 = 40 cm²
Volume = lbh = 6 x 4 x 2 = 48 cm³
Second Figure:
Length (l) = 4 cm
Breadth (b) = 4 cm
Height (h) = 10 cm
Total Surface Area = 2 (lb + bh + hl)
= 2 (4x4 + 4x10 + 10x4)
= 2 (16 + 40 + 40)
= 2 x 96
= 192 cm²
Lateral Surface Area = 2h (l+b) = 2 x 10 x (4+4) = 20 x 16 = 320 cm²
Volume = lbh = 4 x 4 x 10 = 160 cm³
