Answer:
Step-by-step explanation:
The formula of a volume of a rectangular prism:
V = lwh
The fomula of a surface area of a rectangular prism:
SA = 2(lw + lh + wh)
l - length
w - width
h - height
We have l = 10cm, w = 6.5cm and h = 8.3cm. Substitute:
V = (10)(6.5)(8.3) = 539.5 cm³
SA = 2[(10)(6.5) + (10)(8.3) + (6.5)(8.3)] = 2(65 + 83 + 53.95)
= 2(201.95) = 403.9 cm²
