Answer:
Cost of painting = Rs. 729
volume = 729 cm³
Step-by-step explanation:
Side or edge of the cube→ 9cm
Total surfaces area = 6 × side²
= 6 × 9²
= 6 × 81
= 486 cm²
(we found T. surface area because the region in which we are supposed to paint is the all square of the cube)
A.T.Q
Cost of painting 1 Cm² = 1.50 Rs.
.° . 486 cm² = 1.5×486
= 729 Rs.
Volume of cube = Edge³ or Side ³
= 9³
= 729 cm³
(Have a Good Day)
