The ratio of a closed cuboid's length, width, and height is 5: 4: 3. The total surface area of this cuboid is 1500 cm². Find the volume (in cm³) of this cuboid.
The ratio of the l, b, and h = 5: 4: 3 l=5x b=4x h=3x surface area of cuboid = 2(lb +bh +hl) 1500= 2(20x2+12x2+15x2) 750=47x2 x2=750/4 =15.96 x=4 so now the volume of the cuboid = 60×64=3840 cubic cm.
17.5% of 400 – 24% of 150 = ?
3.3 Times 2/27 of 40% of 364=?
2/5 of 3/4 of 7/9 of 14400 = ?
?2 + 114 - 48 ÷ 2 × 5 = 163
(3984 ÷ 24) x (5862 ÷ 40) = ?
2916 ÷ 54 = ? + 27
[(4√ (7) +√ (7))× (7√ (7) + 6√ (7))] - 87 = ?
...95% of 830 - ? % of 2770 = 650
125 ÷ 5 + 14 × 4 = ? + 72 ÷ 4 – 35
