Question

length = 15 cm, breadth= 8 cm, height= 5 cm

​

Answer 1

Step-by-step explanation:

volume = length x breadth x height

= 15 × 8 × 5

= 600cm³

Answer 2

Given :-

Length = 15 cm

Breadth = 8 cm

Height = 6 cm

Concept used:

Total Surface area = 2 × (lb + bh + hl)

l → length, b → breadth , h → height

Calculation:

Total surface area = 2 × (15 × 8 + 8 × 6 + 6 × 15)

Total surface area = 2 × 258 = 516

∴ The surface area is 516 cm^2
